A model of a volcano that is 22 centimeters tall with a volume of 586 point 7 cubic centimeters. What is the area of the base of the model? Round the answer to the nearest tenth.

A cone’s volume is V = (1/3)Bh, where B is the area of its base and h is its height. Rearrange to find the base area: B = 3V/h = (3 × 586.7)/22 ≈ 80.0 square centimeters. The correct choice is 80.0 cm².
