Example Questions

Example Question #1 : Area Of Squares And Rectangles

A square has perimeter 24 feet. Give its area.

Possible Answers:

36 square feet

144 square feet

18 square feet

576 square feet

Correct answer:

36 square feet

Explanation:

The perimeter of a figure is the sum of the lengths of its sides. A square comprises four sides of equal length, so, if the perimeter of the square is 24 feet, then each side has length

$24 \div 4 = 6$ feet.

The area of the square is equal to the length of a side multiplied by itself, so the area of this square is

$6\times6= 36$ square feet.

Example Question #2 : Geometry

Jennifer wants to wallpaper her room which is made up for four rectangular walls each measuring at feet by feet. If each roll of wallpaper covers square feet of space, how many rolls of wallpaper will Jennifer need?

Possible Answers:

Correct answer:

Explanation:

Start by finding out the total square footage of wallpaper needed.

Find the area of one wall. Recall that in order to find the area of a rectangle, you must multiply the length by the width.

$\text{Area of One Wall}=15 \times 12=180$

Since we have four identical walls,

$\text{Total Area of Walls}=4 \times 180 =720$

Now divide this by the amount of square feet covered by each roll of wallpaper to find how many rolls are needed.

$\text{Rolls of wallpaper needed}=\frac{720}{60}=12$

Example Question #1 : Area Of A Circle

Find the area of a circle with the following radius:

r=7

Possible Answers:

$49\pi$

$14\pi$

$7\pi$

$48\pi$

$16\pi$

Correct answer:

$49\pi$

Explanation:

The area of a circle can be calculated using the following formula:

$A=\pi r^2$

In this formula the radius is denoted by the variable, .

Substitute in the known variables and solve for the circle's area.

$A=\pi \times 7^2$

$A=49\pi$

Example Question #33 : Tachs: Math And Ability

Which is equal to the radius of a circle with area $400 \pi$

Possible Answers:

100

200

Correct answer:

Explanation:

The formula for the area of a circle, given its radius , is $A = \pi r^{2}$ . Replace with $400 \pi$ :

$\pi r^{2} = 400 \pi$

To find the radius , first, divide both sides by $\pi$ :

$\frac{\pi r^{2}}{\pi} = \frac{400 \pi}{\pi}$

$r^{2} = 400$

Now, find the square root of both sides. Since $400 = 20 \times 20$ , 20 is the square root of 400, so

r = 20 .

The radius of the given circle is 20.

Example Question #1 : Area

To determine whether a machine on an assembly line is filling bottles with the correct amount of soda, twenty bottles are selected. The tenth bottle and every tenth bottle after that are taken off the line and examined.

This is an example of which kind of sampling?

Possible Answers:

Convenience sampling

Systematic sampling

Stratified sampling

Cluster sampling

Correct answer:

Systematic sampling

Explanation:

The sample in this scenario is selected from the population by choosing obects that occur at regular intervals. That makes this an example of systematic sampling.

Example Question #1 : Area

What is the area of a circle that has a diameter of ?

Possible Answers:

92.6

37.7

452.4

113.1

Correct answer:

113.1

Explanation:

Recall how to find the area of a circle:

$\text{Area of Circle}=\pi \times \text{radius}^2$

To find the length of the radius, divide the diameter by two.

$\text{radius}=\frac{12}{2}=6$

Now, plug it into the equation for the area of a circle.

$\text{Area of Circle}=\pi \times 6^2=36\pi=113.1$
