Question

The area of circle 64 pi what is the diameter of the circle

Answer 1

Answer:

Diameter = 16

Step-by-step explanation:

Area = 64 π

Area = π r²

π r² = 64 π

r² = 64

∴ r = ±8

Radius can't be negative, so r = 8

diameter = 2 x r

               = 2 x 8

Diameter = 16

Hope this helps! :)

Answer 2

Step-by-step explanation:

Diameter = Radius x 2 = 8 x 2 = 16 .
