Question

Circumference of circle is 60pi what is the diameter

Answer 1

$\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\ -----\\ C=60\pi \end{cases}\implies 60\pi =2\pi r\implies \cfrac{60\pi }{2\pi }=r\implies 30=r$

now, recall that the diameter is twice as long as the radius, so it'll be 2*r.

Answer 2

It should be 2. I hope this [email protected]
