Question

A cylinder has a surface area of 1,890 m^2 and a radius of 9 cm what is the volume of the cylinder to the whole number

Answer 1

The answer is ≈ 6214.78

(could put the sign because it wouldnt let me)

Explanation:

Formulas:

`A= {2} \pi r h + 2\pi r^(2)`

`V=\pi r^(2)h`

`V= A (r)/(2) -\pi r^(2) =1890 *(9)/(2) -\pi *9^(3) = 6214.77896`

rounded= 6214.78
