what is the volume of the cylinder with the radius of 3 and height of 8
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 = 3, and L = 8. Then
V = πR^2.L = π(3)^2(8) = 72π
Volume is: V = 72π m^3
