A paint tin is a frustum with end radii 14 cm and 4 cm and a depth of 9 cm. Find its volume, in cm³. (Take \π = 3.14 .)

Question

Accepted Answer

2524.56. V = 1/3 × 3.14 × 9 × (196 + 16 + 56) = 3.14 × 3 × 268 = 2524.56 cm³. 1997.04 drops the Rr term (212 instead of 268); 7573.68 forgets the 1/3 ; 942 uses (R - r)^2 = 100 in place of R^2 + r^2 + Rr .
