Question

The diameter of a circle is 12 cm. Find its circumference in pi

Answer 1

C=12π

C≈37.69911 cm

Explanation:

d=2r, with d being diameter and r being the radius.

C=2πr, with C being the circumference and r being the radius.

Therefore, C=πd.

C=πd

C=π(12)

C=12π

C≈37.69911 cm

Hope this helps and good luck on your homework!

Answer 2

12π

Explanation:

We Know

Circumference of a circle = d x π

d = 12 cm

Find its circumference in pi.

Let's solve

12 x π = 12π

So, the circumference of the circle is 12π
