The radius of a circle is 12 in. Find its circumference in terms of
π
π.

It would be 24(π)

Step-by-step explanation:

This is due to the circumfenrece equation for a circle being (π)D, with D as the diameter which is 2x the radius, so 12x2=24.

After this, it is 24(π), though leave it at there since it is meant to be written in terms of it. You're now done!
