Question

Find the area of the circle with a circumference of

30
π
. Use 3.14 for
π
. Round to the nearest hundredth.

Area in in decimal form: ______

Options:

Answer 1

706.50 mm^2

Explanation:

The formula to find the circumference is 2πr (r : radius)

if the circumference is 30π the the radius is = 15

to find the area we use the following formula :

π*r^2

r = 15 and π is given as 3.14

(3.14)*15^2 = 706.50 mm^2
