Question

Find the volume of a right circular cone that has a height of 15 ft and a base with a radius of 7.9 ft. Round your answer to the nearest tenth of a cubic foot

Answer 1

the volume of a right cone can be found by the formula

`V=\pi\cdot r^2\cdot(h)/(3)`

replace in the formula

`\begin{gathered} V=(7.9ft)^2\cdot((15ft))/(3)\cdot\pi \\ V=\pi\cdot312.05ft^3^{} \end{gathered}`

multiply and round to find the final result

`\begin{gathered} V=980.333ft^3 \\ V\approx980.3ft^3 \end{gathered}`
