A drinking glass is shaped like a frustum of a cone. Its two circular ends have radii 2 cm and 1 cm and the height is 14 cm. Find the capacity of the glass, in cm^3 (use π = 22/7).

Question

Accepted Answer

102.67. V = 1/3*π*h*(R^2 + r^2 + R*r) = 1/3*22/7*14*(4 + 1 + 2) = 1/3*22/7*14*7 = 1/3*22*14 = 308/3 = 102.67 cm^3.
