The diameter of a circle of 255 π is:
melisa1 [442]

Hello from MrBillDoesMath!

Answer:   30


Discussion:

The area of a circle of radius R is given by the formula  

Pi * R^2

We are given that  the area is 225 Pi (Not 255 Pi as stated by the author)

Pi * R^2 = 225 * Pi

Divide both sides by Pi :

R^2 = 225  --->  R = 15

The diameter is twice the radius so the diameter = 30.
