Question

The diameter of a circle is 16 meters. what is the circle's circumference

Answer 1

16pi

or

50.2654.. rounded to whichever number place

Explanation:

The circumference of a circle is 2 (3.14)r which is the same as d (3.14) becasue the diameter is twice the size of the radius.

AS A result plug in what you know

d=16 meters

SO answer is 16 (3.14) in PI terms

Answer 2

16π

Explanation:

To find circumference, the formula is 2πr

To find radius divide the diameter by 2. So, 16/2=8

2π(8)

8 x 2=16

16π
