Question

Mrs. Beasley is asking students to find the volume of the cylinder below using 3.14 for pi. Which student wrote the correct expression for the value of B, the area of the base

Answer 1

Brittany (3.14)(4)

Explanation:

Answer 2

`A=3.14* r^(2)`

Explanation:

The volume of a cylinder is given as the product of surface area and height.

V=Ah

But the surface area is given by

`A=\pi r^(2)`

Taking value of
`\pi` as 3.14 then the surface area is

`A=3.14* r^(2)`

Therefore, the volume being V=Ah hence

`V=3.14* r^(2)* h`

This question only wants us to establish the surface area hence

`A=3.14* r^(2)`
