9 cm
Enter P

Answer 1

`\sf{\qquad\qquad\huge\underline{{\sf Answer}}}`

Here we go ~

• take value of pi = 3

• r = radius = 5 cm

• h = height = 9 cm

Let's calculate volume of Cylinder ~

`\qquad \sf  \dashrightarrow \:v = \pi {r}^(2) h`

`\qquad \sf  \dashrightarrow \:v = 3 * {5}^(2) * 9`

`\qquad \sf  \dashrightarrow \:v = 3*25 * 9`

`\qquad \sf  \dashrightarrow \:v = 75 * 9`

`\qquad \sf  \dashrightarrow \:v =67 5 \: \: cm {}^(3)`

That's all, ask me if you have any queries ~

Answer 2

Given:

• r= 5 cm
• h= 9 cm

Note that:

• r: radius
• h: height

To find:

• The volume of the given cylinder by using π as 3

Solution:

• A cylinder is a three dimensional shape with two circular bases at the end with equal circular cross section.

`\large\boxed{\bold{V= \pi{r}^(2)h}}`

`\large\boxed{\bold{\red\pi\red=\red3}}`

In this question all the values are given so we'll simply have to substitute and solve.

Let's solve!

We are asked to use 3 as π.

So we'll have to multiply 3, 5 squared and 9.

We'll have to give our answer in cubic centimeter.

Let's substitute the values according to the formula.

`V= 3*{5}^(2)*9`

`\large\boxed{\bold{V= 675 \: {cm}^(3)}}`

The answer is a whole number so we won't have to round off.

Therefore, the volume of the given cylinder is 675 cubic centimeters.
