Question

A construction cone has a diameter of 8 inches and a height of 16 inches. What is the volume of the construction cone? Round your answer to the nearest hundredth.

Answer 1

volume of cone = 1/3 pi r^2 h

since you have diameter turn it into radius first

radius = diameter/2
radius = 8/2
radius = 4

now put this into the equation
\[V = \frac 13 \pi r^2 h\]
\[V = \frac 13 \pi \times (4)^2 \times 16\]
got it?
