Answer 1

Answer:

942.48

Step-by-step explanation:

5 squared times 12=300 times pi=volume

Answer 2

Answer:

The volume of cylinder is 300π m³.

Step-by-step explanation:

First, you have to find the radius of cylinder. Given that the diameter of cylinder is 10m so in order to find radius, you have to divide it by 2 :

$radius = diameter \div 2$

Let diameter = 10,

$radius = 10 \div 2$

$radius = 5 \: metres$

Next, you have to use the volume of cylinder, V = π×r²×h where r represents radius and h ia height. Then, you have to substitute the following values into the formula :

$v = \pi \times {r}^{2} \times h$

Let r = 5,

Let h = 12,

$v = \pi \times {5}^{2} \times 12$

$v = \pi \times 25 \times 12$

$v = 300\pi \: {m}^{3}$
