Question

finding the area of a circle > find the radius of each circle. show your work. 1 12 in. 2 26 in.

Explanation:

Step1: Identify given diameter

For circle 1, diameter $d = 12$ in. Radius $r$ is half of diameter.
$r=\frac{d}{2}$

Step2: Calculate radius

For circle 1, $r=\frac{12}{2}=6$ in.
For circle 2, diameter $d = 26$ in, so $r=\frac{26}{2}=13$ in.

Answer:

1. $6$ in
2. $13$ in
