What is the approximate diameter of Sharon’s hula hoop if the circumference is 88 inches?

To find the diameter of a circle when you know the circumference, you can use the formula:

C = \pi \times d

where ( C ) is the circumference and ( d ) is the diameter. You can rearrange this formula to solve for the diameter:

d = \frac{C}{\pi}

Given that the circumference ( C ) is ( 88 ) inches, you can substitute this value into the formula:

d = \frac{88}{\pi}

Using an approximate value for (\pi), which is (3.14159), the calculation becomes:

d \approx \frac{88}{3.14159} \approx 28.014

So, the approximate diameter of the hula hoop is 28.0 inches.

The correct answer choice is C. 28.0 inches.

What is the radius of a circle with a circumference of (60\pi) units?

The formula for the circumference of a circle is:

C = 2\pi r

where ( C ) is the circumference and ( r ) is the radius.

Given the circumference ( C = 60\pi ), you can set up the equation:

60\pi = 2\pi r

To find the radius, ( r ), you can divide both sides of the equation by ( 2\pi ):

r = \frac{60\pi}{2\pi}

The (\pi) terms cancel out, simplifying the expression to:

r = \frac{60}{2} = 30

So, the radius of the circle is 30 units.

The correct answer choice is B. 30 units.

Which measurement is closest to the circumference of a compact disc with a diameter of 4.75 inches?

The formula for the circumference ( C ) of a circle is given by:

C = \pi \times d

where ( d ) is the diameter. Given that the diameter ( d ) is ( 4.75 ) inches, the circumference can be calculated as:

C = \pi \times 4.75

Using the approximate value of (\pi ) which is (3.14159), we get:

C \approx 3.14159 \times 4.75 \approx 14.9225

Therefore, the measurement closest to the circumference of the compact disc is 14.92 inches.

The correct answer choice is B. 14.92 inches.

What is the area of a circle if the diameter is 6 centimeters? Use 3.14 for (\pi).

To find the area of a circle, you can use the formula:

A = \pi r^2

First, calculate the radius (r) from the diameter. The radius is half of the diameter, so:

r = \frac{6}{2} = 3 \, \text{centimeters}

Now, substitute the radius (r = 3) and (\pi = 3.14) into the area formula:

[
A = 3.14 \times (3)^2
]

[
A = 3.14 \times 9
]

A = 28.26 \, \text{square centimeters}

Therefore, the area of the circle is 28.26 square centimeters.

The correct answer choice is B. 28.26 square centimeters.
