Question

find the area of a circle with a circumference of 18.64 units

Answer 1

The answer is, A≈ 27.65

Answer 2

Answer:

A=86.8624pi units or A = 272.747936 units

Step-by-step explanation:

Circumference = 2(pi)r

18.64=2(pi)r

r=18.64/2pi

r=9.32pi

Area = pi(r^2)

A = pi(9.32^2)

A=86.8624pi units

or A = 272.747936 units
