Question

Find the volume of this cone.Use 3 for T.10 ft=115 ftTr²hV=3Hint: The radius (1) is1/2 of the diameter.V ~ [?]ft3

Answer 1

Given:-

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

To find the volume of the cone.

From the given image it is clear,

`h=5,r=5`

So now we substitute the known values. so we get,

`\begin{gathered} V=(\pi r^2h)/(3) \\ V=(3(5)^25)/(3) \\ V=5^3 \\ V=125 \end{gathered}`

So the required volume is 125ft^3.
