Question

Which point on the number line represents the approximate volume of a cone with a radius of 3 units and a height of 4 units? Use 3.14 for π.

Answer 1

37.68 cubic units

Explanation:

Volume of a cone = πr²
`(h)/(3)`

Volume = 3.14 * 3² *
`(4)/(3)`

Volume = 3.14 * 9 *
`(4)/(3)`

Volume = 3.14 * 3 * 4...(we can cancel out the 3 by dividing 9 by 3)

Volume = 3.14 * 12

Volume = 37.68 cubic units
