Question

find the missing measurement of each circle. what is the length of the radius? label your answer on the circle. 12.6 in

Explanation:

Step1: Recall radius - diameter relationship

The diameter $d$ of a circle is twice the radius $r$, i.e., $d = 2r$. Here, the diameter $d=12.6$ in.

Step2: Solve for radius

We can rewrite the formula as $r=\frac{d}{2}$. Substituting $d = 12.6$ in, we get $r=\frac{12.6}{2}=6.3$ in.

Answer:

$6.3$ in
