Question

A cylinder has a radius of 10 m and a height of 8 m what is the exact volume of he cylinder

Answer 1

Answer:

V = 800π

Step-by-step explanation:

The formula for volume of a cylinder is V = πr²h  where r is the radius of the base circle, and h is the height of the cylinder

We are given r = 10, and h = 8.  Plug them in and solve for V...

V = π(10²)(8)

    V = π(100)(8)

          V = 800π

This is the EXACT answer.  Leave it in terms of pi.  If you multiply out pi, you have to round, then you have an estimated answer.

Answer 2

$\bf \textit{volume of a cylinder}\\\\ V = \pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=10\\ h=8 \end{cases}\implies V=\pi (10)^2(8) \\\\\\ V=800\pi \implies V\approx 2513.27$
