Answer:
r = Sqrt(81.2)
Step-by-step explanation:
V = pi * r^2 * h
255 = pi * r^2 * 1
255 = pi * r^2
255/pi = r^2
81.2 = r^2
Sqrt(81.2) = r
The radius of the cylinder with the volume of a cylinder is 225 cubic inches will be 9.21 inches.
How to calculate the volume of a cylinder?
The volume of the cylinder is calculated by multiplying the area of the base and the height. Since the base is a circle, we use the formula for the area of a circle times the height of that cylinder.
So the formula is:
[tex]V = \pi * r^2 * h[/tex]
where:
- V=255
- h=1
In this case we find:
[tex]255 = \pi * r^2 * 1\\255 = 3 * r^2\\255/3 = r^2\\r^2=85\\r=9.21[/tex]
