Question

What is the length of the radius, r? 6 cm 18 cm 36 cm 72 cm.

Answer 1

The length of the radius of circle o is 18 cm.

Given that

Circle o has a circumference of 36π cm.

We have to determine

What is the length of the radius, r?

According to the question

Circle o has a circumference of 36π cm.

The length of the radius of the circle is determined by the following formula;

$\rm Circumference = 2\pi r$

Substitute all the values in the formula;

$\rm Circumference = 2\pi r\\ \\ 36\pi =2\pi r\\ \\ r = \dfrac{36\pi }{2\pi }\\ \\ r = 18 \ cm$

Hence, the length of the radius of circle o is 18 cm.
