Chapter 1.4, Problem 58AYU

To determine

To find: the radius of a circle

Answer to Problem 58AYU

Therefore, the radius of the circle is $3$

Explanation of Solution

Given:

The circumference of a circle = $6\pi$ .

Formula used:

The circumference of a circle is $2\pi r$ .

It is given that the circumference of the circle is $6\pi$ .

Thus,

  $2\pi r=6\pi$ .

Divide both sides by $2\pi$ .

  $\begin{array}{l}\frac{2\pi r}{2\pi }=\frac{6\pi }{2\pi }\\ r=3\end{array}$

Therefore, the radius of the circle is $3$ .

Conclusion:

Therefore, the radius of the circle is $3$ .
