Question

Find the volume of a cylinder if it has a diameter of 8 and a height of 12. Leave your answer in terms of π. A) 64π B) 192π C) 256π D) 768π

Answer 1

Now, if the diameter is 8 units, then the radius is half that, or 4.

$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h\quad \begin{cases} r=radius\\ h=height\\ ------\\ r=4\\ h=12 \end{cases}\implies V=\pi 4^2\cdot 12\implies V=192\pi$

Answer 2

Its B) 192π~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`
