Question

A drinking glass is in the shape of a frustum with top radius 7 cm, bottom radius 3.5 cm and height 12 cm. Find its capacity (use π = 22/7, answer in cm^3 to two decimals).

Accepted Answer

1078. V = 1/3 π h (R^2 + Rr + r^2) = (1/3)(22/7)(12)(49 + 24.5 + 12.25) = (1/3)(22/7)(12)(85.75) = 22 × 12 × 85.75/21 = 22638/21 = 1078.00 cm^3.
