6) A cylindrical shaped silo has a diameter of 18 feet and a height of 4 feet. How much water can the silo hold, in terms of π?

Natali5045456 [20]

The amount of water silo can hold in terms of π is 324π cubic feet

<h3><u>Solution:</u></h3>

Given that cylindrical shaped silo has a diameter of 18 feet and a height of 4 feet

To find: Amount of water silo can hold in terms of π

This means we are asked to find the volume of cylindrical shaped silo

<em><u>The volume of cylinder is given as:</u></em>

$\text {volume of cylinder }=\pi \mathrm{r}^{2} \mathrm{h}$

Where "r" is the radius of cylinder

"h" is the height of cylinder

π is the constant has a value 3.14

Given diameter = 18 feet

$radius = \frac{diameter}{2} = \frac{18}{2} = 9$

Substituting the values in formula, we get

$\text {volume of cylinder }=\pi \times 9^{2} \times 4$

$\text {volume of cylinder }=\pi \times 81 \times 4=324 \pi$

Thus amount of water silo can hold in terms of π is 324π cubic feet
