Riya makes a wooden toy by fixing a cone of radius 3.5 cm and height 12 cm on top of a hemisphere of radius 3.5 cm. What is the total volume of the toy? (use π = 22/7, answer to two decimals in cm^3.)

Question

Accepted Answer

243.83. Cone = 1/3 π r^2 h = (1/3)(22/7)(12.25)(12) = 22 × 12.25 × 12/21 = 3234/21 = 154.00. Hemisphere = 2/3 π r^3 = (2/3)(22/7)(42.875) = 89.83. Total = 154.00 + 89.83 = 243.83 cm^3.
