A large pizza has a diameter of 16 inches. Which of the following is the area of the pizza in terms of pi (π)? 

A. 16 πin2

B. 64 πin2

C. 32πin2

D. 256 πin2

Answer Explanation:

We are told to find the area of the pizza given its diameter. The pizza is in circular form, and its area is found as:

However, we are not given r, which is the radius of the circle. But we can find it from the given diameter as

Substituting r=8 in the equation of the area of a circle

Thus, the area of the pizza is 64  in2.

NOTE:  (Pi) remains as a symbol because values of Pi can vary from 22/7 to 3.1415 to 3.14 and so forth.

Therefore, the Correct Answer is B.

  • Q #1: The data below represents students’ test scores. Which of the following is the median of the set data? 11, 12, 18, 14, 22, 17, 17, 12, 26, 12, 13

    A. 15

    B. 12

    C. 14

    D. 15.8

    Answer Explanation

    the median of a data set is the element that is found on the middle position. It is found by organizing the elements from the smallest to largest.

    The data set above arranged from the smallest to largest is:

    11, 12, 12, 12, 13, 14, 17, 17, 18, 22, 26

    The number of elements is odd and the median is found in the (N+1)/2 th position. Here N=11, and the median falls in (11+1)/2=12/2=6 th position.

    The element 14 falls in the 6th position, which is our median of the given data set.

  • Q #2: Which of the following statements is true about the graph?  

    A. The Chargers points per game decreased between seasons eight times between 1996 and 2015

    B. The Chargers scored their lowest number of points per game in 1999-2000 season

    C. The Chargers scored their greatest number of points per game in the 2008-09 season

    D. None of the above

    Answer Explanation

    To find the true statement we need to analyze the given statements.

    For statement 1: the points per game decreased five times between 1996 and 2015. So, the statement is false.

    For statement 2: the lowest points scored per game was in 1998-99 season. So, the statement is false.

    For statement 3: 2008-09 was the season the chargers scored the greatest number of points per game. So, this statement is true.

  • Q #3: A student performs the following estimations. 24+190≈210 151+319≈470 974+1022≈1990 Based on these estimations, which of the following is the student’s estimate of 452+5017?

    A. 5470

    B. 5500

    C. 5400

    D. 5450

    Answer Explanation

    from the given estimations, we can find the actual addition of the numbers and see a trend the student utilizes to find their estimates. The exact sum is as follows

    24+190=214

    151+319=470

    974+1022=1996

    From the above evaluation, we can clearly see the students approximates the value in the ones values. So, in the problem we need to approximate 452+5017.

    452+5017=5469

    We can approximate 5469 based on the provided choices to 5470.

  • Q #4: 4(x-5)=8 Solve the equation above for x. Which of the following is the correct answer?

    A. ¾

    B. 3 ¼

    C. -3

    D. 7

    Answer Explanation

    In order to solve for the value of x, we use the order of operations as follows:

    The first step is to divide both sides by 4

    Since 5 is subtracted, we add 5 to both sides to eliminate it from the left-hand side of the equation

    Thus, the value of x is 7.

  • Q #5: When the weights of the newborn babies are graphed, the distribution of weights is symmetric with the majority of weights centered around a single peak. Which of the following describes the shape of this distribution?

    A. Uniform

    B. Bell-shaped

    C. Skewed right

    D. Bimodal

    Answer Explanation

    Since the distribution is symmetric, the mean, mode, and median will all be equal. The shape of the distribution will be bell-shaped.

  • Q #6: Four friends are sharing a pizza. One friend eats half of the pizza. The other three friends equally divide the rest among themselves. What portion of the pizza did each of the other three friends receive?

    A. 1/6

    B. 1/3

    C. ¼

    D. 1/5

    Answer Explanation

    we are needed to find the portion of pizza shared by 3 three friends. We treat the whole pizza as 1. Now, 1 friend eats half of the whole pizza. Thus,

    One friend=1/2 of 1=1/2*1=1/2

    Remaining amount=1-1/2=2/2-1/2=1/2

    Thus, ½ of pizza is left for three friends to share among themselves. Then, each friend will get

    So, the other three friends will each get 1/6 of the pizza.

  • Q #7: Which of the following values is the greatest?

    A. 9/2

    B. 4.4

    C. 10/3

    D. 4.25

    Answer Explanation

    The initial step is to convert the decimal numbers into fractions.

    4.4 becomes 44/10

    4.25 becomes 425/100

    Thus, the set of fractions is 9/2, 44/10, 10/3, 425/100. The least common denominator for 2, 10, 3, and 100 is 300, which we use to compare each options given.

    9/2*300=1350

    44/10*300=1320

    10/3*300=1000

    425/100*300=1275

    From the above, 1350 is the greatest value which corresponds to 9/2. Thus, 9/2 is the greatest value of all the choices given.

  • Q #8: A circle has an area of 49π in2. Which of the following is the circumference of the circle in terms of pi (π)?

    A. 14 π in

    B. 28 π in

    C. 7 π in

    D. 3.5 π in

    Answer Explanation

    The initial step is to establish the relationship between area of a circle and the radius. The area of the circle is given by the formula

    Now, substituting the 49 π in2 in place of A in the equation above becomes:

    We want to find r, therefore, we rearrange the equation as

    Divide both sides by

    Take square root both sides of the equation

    The radius of the circle is 7 in, and the circumference of the circle is determined as follows

    Substituting the value of r=7 becomes

    Thus, the circumference of a circle whose area is 49  in2 is 14  

  • Q #9: A nurse earns $800.00 per week before any tax deductions. The following taxes are deducted each week: $83.00 federal income tax, $38.00 state income tax, and $79.00 Social Security tax. How much will the nurse make in 4 weeks after taxes are deducted?

    A. $2,600.00

    B. $3,000.00

    C. $2,400.00

    D. $2,800.00

    Answer Explanation

    we need to find the net income of the nurse in 4 weeks from the weekly net income.

    Weekly net income=gross income-total tax

    Total tax=federal income tax+state income tax+Social Security tax

    Total tax=$(83.00+38.00+79.00)

    Total tax=$200.00

    Weekly net income=$(800.00-200.00)=$600.00

    In one week, the net income of the nurse is $600.00 and in 4 weeks the nurse will a net income of:

    The nurse will earn $2,400.00 in 4 weeks after taxes are deducted.
