Question

What is the circumference of a circle with a diameter of 16 in?

Answer 1

`16pi ~~ 50.27` in.

Explanation:

The circumference of a circle is given by the formula `2pi*r` where `r` is the radius. The circumference is therefore `pi*d` where `d` is the diameter `(d =2r)`
If `d=16` circumference is `16pi ~~ 50.27`
