Question

The radius of a circle is 3 m. Find its circumference in terms of pi.

Answer 1

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

• r is the radius  --> 3m

Circumference = $2\pi (3) = 6\pi$

It says to leave in terms of pi which means that we won't solve $6\pi$

Thus the answer is $6\pi$.

Hope that helped!
