volume of cylinder in cubic in if the radius is 10 in and the height is 40 in?
If you have a cylinder and know its radius and its length, then you can work out its volume.
Volume is given by, V = πR^2.L,
where R is the radius and L is the length.
We have R = 10 in, and L = 40 in. Then
V = πR^2.L = π(10)^2(40) = 4,000π
Volume is: V = 4,000π m^3
