The circumference of a circle is 15 pi centimeters what is the area of the circle in terms of pi

[225(pi)]/4

Step-by-step explanation:

circumference = pi(diameter)

area = pi (radius)^2

Diameter = 2(radius)

15pi cm = pi(diameter)

divide both sides by pi

diameter = 15

radius = 7.5

Area = pi (7.5)^2

A  = 56.25 pi

most teachers prefer fractions so

225pi/4
