Question

Find the radius of a circle with a circumference of 12.6 yd

Answer 1

Answer: approximately 2yd

Step-by-step explanation:

There are two ways in which you can do this. First, remember the circumference formula.

$C=\pi d$

Solve for diameter.

$d=\frac{C}{\pi}$

$d=\frac{12.6yd}{3.14}$

$d=4$

Divide the diameter by 2.

$r=\frac{d}{2}=\frac{4}{2} =2$
