Question

If the circumference of a circle measures 8π cm, what is the area of the circle in terms of π?

Answer 1

ans is 16pi cm2

Explanation:

Circumference = Dia x pi = 8pi

Dia = 8

Area = Dia^2 x pi / 4 = 8^2 x pi / 4 =64 x pi /4

= 16pi

Answer 2

16π cm^2

Explanation:

circumference of a circle = 2 * radius * π = 8π cm

so radius = 4 cm

area of a circle = radius * radius * π

= 4 * 4 * π

= 16π cm^2
