what is the volume of the cylinder of 3.5in by 7.5in?
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 = 3.5 in, and L = 7.5 in. Then
V = πR^2.L = π(3.5)^2(7.5) = 91.875π
Volume is: V = 91.875π in^3
