Question

PLEASE ANSWER ASAP What is the volume of a cylinder with height 10 and diameter 9? (Round to 2 decimal places.)

Answer 1

The volume of the cylinder is equal to

`V=635.85\ units^(3)` or
`V=202.50\pi \ units^(3)`

Explanation:

we know that

The volume of the cylinder is equal to

`V=\pi r^(2) h`

we have

`r=9/2=4.5\ units` -----> the radius is half the diameter

`h=10\ units`

substitute

`V=\pi (4.5)^(2)(10)=202.50\pi \ units^(3)` -----> exact value

assume

`\pi =3.14`

`V=202.50(3.14)=635.85\ units^(3)` -----> approximate value
