Question

dius of each circle. 3) radius: ____________ circumference: 25.12 in

Explanation:

Step1: Recall the circumference formula

The formula for the circumference of a circle is $C = 2\pi r$, where $C$ is the circumference and $r$ is the radius.

Step2: Solve for the radius

Given $C = 25.12$ in, we can rewrite the formula as $r=\frac{C}{2\pi}$. Substituting $C = 25.12$ in and taking $\pi\approx3.14$, we have $r=\frac{25.12}{2\times3.14}$.
$r=\frac{25.12}{6.28}=4$ in.

Answer:

4 in
