What is the circumference of a pool if the radius is 5m?

Multiply the radius by 2, then multiply that result by the value of Pi - and you'll have your answer.

How do you get the diameter from the radius?

to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius

To get the volume of a multiply pi by the radius squared and then multiply by the height.?

That is correct for finding the volume of a cylinder.

How do you find the area of circles if you have the diameter?

you take the diameter and divide it in half then you have the radius. Take the radius and multiply the radius by its self (radius squared) then multiply by 3.14 (pi) example: Diameter is 24 find the area. 24 divided by 2 is 12 12x12= 144 144x3.14= 452.16

Find the circumference of 15cm radus circle?

15mm what? Diameter or radius? Formula for finding Circumference is Pi X Diameter. If 15mm is the Diameter, multiply 15mm by 3,1614 = 47.124mm. If 15mm is Radius, then multiply Radius by 2 to get Diameter and then multiply by 3.1416 = 15 X 2 = 30 X 3.1416 = 94.248mm.
