A solid iron pole consists of a cylinder of radius 7 cm and height 20 cm surmounted by a cone of the same radius and height 9 cm. Find the total volume of the pole (use π = 22/7, answer in cm^3).

Question

Accepted Answer

3542. Cylinder = π r^2 h = (22/7)(49)(20) = 22 x 7 x 20 = 3080. Cone = 1/3 π r^2 h = (1/3)(22/7)(49)(9) = 22 × 7 × 9/3 = 1386/3 = 462. Total = 3080 + 462 = 3542 cm^3.
