Question

What is the exact volume of the cone?

28π in³
563π in³
1963π in³
196π in³

Answer 1

28π in^3

56/3π in^3

196/3π in^3

196π in^3

These are the numbers they meant to put and the answer is 196/3 in^3.

Answer 2

`\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}\qquad \begin{cases} r=radius\\ h=height\\ ------\\ r=7\\ h=4 \end{cases}\implies V=\cfrac{\pi \cdot 7^2\cdot 4}{3}\implies V\approx 205.25`
