Question

The area of the circle above is 200.96 units? What is the circumference of the circle? Use a = 3.14.

Circumference = 2777
Area = 792
A. 50.24 units
B. 25.12 units
C. 100.48 units
D. 66.99 units

Answer 1

50.24

Explanation:

Area = 200.96

Let's find the raidus from the area formula.

200.96 = π · r^2

Divide both sides by π !

64 = r^2

square root both sides

r = 8.

Now since we know the raidus we can find the circumferewnce.

-

c=2πr

c=2*3.14*8

c= 50.24
