Question

If a cone has a diameter of 4 I'm and a height of 11.cm, what is the volume of the cone?

Answer 1

Volume of a cone is represented by the following expression:

`\begin{gathered} V=(1)/(3)\pi\cdot r^2\cdot h \\ \text{where, } \\ r=\text{radius} \\ \pi=\text{constant=3.1416} \\ h=\text{height} \end{gathered}`

With the information given, we can substitute and find the volume:

`\begin{gathered} V=(1)/(3)\cdot\pi\cdot(2)^2\cdot11.5 \\ V=(46)/(3)\pi \\ V=48.17cm^3 \\ V\approx48.2^{} \end{gathered}`
