Question

a storage drum in the shape of a cylinder is 3 feet tall and has a diameter of 4 feet. what is the total surface area of the storage drum? use 3.14 for pi and round the answer to the nearest tenth

Answer 1

SA=62.8\ ft^2

Explanation:

Answer 2

`SA=62.8\ ft^2`

Explanation:

we know that

The surface area of a cylinder is equal to

`SA=2\pi r^(2)+2\pi rh`

we have

`h=3\ ft`

`r=4/2=2\ ft` ----> the radius is half the diameter

assume

`\pi =3.14`

substitute

`SA=2(3.14)(2)^(2)+2(3.14)(2)(3)`

`SA=62.8\ ft^2`
