Question

Find the exact area of a circle having the given circumference.

4(sqrt3pi)

Answer 1

find the Radius first.

Answer 2

Use the equation for circumference C = 2pi*r.

Solve for r and then use that value in the equation for area A = pi*r^2

Answer 3

C = pi d
4(sqrt3pi)
-------- = d
pi

Answer 4

d = 12.28
r = 6.14units

Answer 5

Area = pi r^2
= pi (6.12)^2
=118.44unitssq

Answer 6
