Question

A volcano in the approximate shape of a cone has a diameter of 16 km and a height of 1.95 km. Which estimate best approximates the volume of the volcano? Use 3.14 for pi and round to nearest whole number.

Answer 1

To find the approximate volume of the volcano, you will use the formula for finding the volume of a cone.

V = 1/3 x pi x r^2 x h
     1/3 x 3.14 x 8^2 x 1.95
V = 130.624

The approximate volume of the volcano is 131 cubic kilometers.
