How To Calculate The Volume Of A Hollow Cylinder?

Answer Question

1 Answer - Sort by: Date | Rating

    To calculate the volume of a hollow cylinder, you first need to find the area of the base of the cylinder. Cylinders have circular bases so the area can be calculated by pi x (radius)2 where pi is always 3.14. The radius is equal to half of the diameter which is the length of the line drawn from one point to the other of the circle in the center. Suppose the circle has a radius of 10cm.
    So, the area would be 3.14 x (10)2 = 314cm2
    Now to get the volume of the cylinder, you need to multiply the area of the base into the height of the cylinder. The height is the perpendicular distance between the base of the cylinder and its top, or rather its depth.
    Suppose the depth of the cylinder is 10cm too. So, you multiply the area of the base with 10:
    314x10=3140cm3.

    The volume of the cylinder is, therefore, 3140cm3.
