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 ~

$\qquad \sf  \dashrightarrow \:v = \pi {r}^{2} h$

$\qquad \sf  \dashrightarrow \:v = 3 \times {5}^{2} \times 9$

$\qquad \sf  \dashrightarrow \:v = 3\times25 \times 9$

$\qquad \sf  \dashrightarrow \:v = 75 \times 9$

$\qquad \sf  \dashrightarrow \:v =67 5 \: \: cm {}^{3}$

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.

$V= 3\times{5}^{2}\times9$

$\large\boxed{\bold{V= 675 \: {cm}^{3}}}$

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.
