Question

Find the volume of this cylinder. Use 3 for a.10 inV = 7r2h11 inV V [?]in3

Answer 1

Given that the diameter of the cylinder is 10 in and height h=11 in.

$We\text{ know that radius =}\frac{\text{diameter}}{2}=\frac{10}{2}=5\text{ in.}$

The formula for the volume of the cylinder is

$V=\pi r^2h$$\text{Substitute }\pi=3,\text{ r=5 and h=11, we get}$

$V\approx3\times5^2\times11$

$V\approx3\times25\times11$

$V\approx825in^3$

Hence the required volume of the given cylinder is

$V\approx825in^3$
