Question

A silo is a building shaped like a cylinder used to store grain. The diameter of a particular silo is 6.5 meters, and the height of the silo is 12 meters. 6.5 m 12 m Which equation can be used to find the volume of this sito in cubic meters? CAVE (3.25 (12) V = *(6.5) (12) Cy=+(12)? 3.25) DV=(6) (6.5)

Answer 1

A) V = π (3.25)² (12)

Step-by-step explanation

The volume of a cylinder is:

`V=B\cdot h`

Where B is the area of the base and h is the heigth. The area of the base is:

`B=\pi r^2`

r is the radius of the base. If we replace this into the expression for the volume we get:

`V=\pi r^2h`

In this problem the heigth of the cylinder is 12m. The diameter is 6.5m and the radius - which is half the diameter - is 3.25m. Then the volume is:

`V=\pi(3.25)^2(12)`
