Question

A flying disc in the shape of a circle has a circumference of 8 inches. What is the radius of the flying disc.

Answer 1

Answer:

A.

Step-by-step explanation:

The formula for circumference is:

$C=2\pi r$

We know that the circumference is 8π inches. So, substitute 8π for C:

$8\pi =2\pi r$

Solve for r. Divide both sides by 2π. So:

$r=\frac{8\pi}{2\pi}=4$

Therefore, the radius is 4 inches.

Hence, our answer is A.
