Question

Find the volume of the cylinders. (Use π=3.14)
A. Height= 9ft ; radius= 3ft
B. Radius=13yd; height=8yd

Answer 1

Given:

Question 1

• h= 9 ft
• r= 3 ft

Question 2

• h= 8 yd
• r= 13 yd

Note that:

• h= height
• r= radius

To find:

The volume of the given cylinders.

Solution:

$\huge\boxed{Formula: V=\pi{r}^{2}h}$

$\huge\boxed{\red \pi \red = \red 3 \red . \red 1 \red 4}$

Let's solve!

Substitute the values according to the formula.

$V=3.14×{3}^{2}×9$

$\large\boxed{V= 254.34 \: {ft}^{3}}$

Let's work on question 2

Substitute the values according to the formula.

$V=3.14×{13}^{2}×8$

$\large\boxed{V= 4245.28 \: {yd}^{3}}$
