Answer:
The radius of cylinder is 12in
Explanation:
pi is written mathematically as π
The volume of a cylinder, v = πr²h
We are given, v = 144π
height of the cylinder, h = 1in
Therefore, 144π = π x r² x 1
To make r² of formula, we divide both sides by π x 1 = π
144π/π = (π x r² x 1) / π
r² = 144
We take the square root of both sides to find the value of r
√r² = √144
r = 12
Therefore, radius of the cylinder, r is 12in
