Question

24) area = 16 (pi) inches squared. Find the diameter.​

Answer 1

pi r *2 = 16 pi

r*2=16

r= squre root of 16 = 4

diameter = 2r = 8 units

Answer 2

8 inches

Explanation:

The area of a circle is:

A = π
`r^(2)`

We know the area is 16π

16π = π
`r^(2)`

16 =
`r^(2)`

Taking the square root of both sides.

4 = r

The diameter is 2 times the radius.

D = 2r.

D = 2(4) = 8 inches
