Question

A cone has a diameter of 9 inches and a height of 12 inches. Find the volume of the cone to the nearest tenth.

972 in³
254.3 in³
324 in³
113 in³

Answer 1

For the radius we just divide the diameter in half

Answer 2

Which is 4.5

Answer 3

So we just plug in for our radius and height

Answer 4

\[V=\pi4.5^2\frac{ 12 }{ 3 }\]

Answer 5

\[\pi \times20.25\]

Answer 6

63.585x4=254.34

Answer 7

V=254.34 or if you were to use google V=254.47

Answer 8

To the nearest tenth it would be 254.3 in

Answer 9

Sorry, I was afk. Thanks soooo much :D
