Question

Now I want to cover the curved area of the vase in paper. I do not want to cover the bases. My vase has a 6” diameter and is 12” tall. How many square inches of paper will I need?

Answer 1

`226.08\ in^(2)` or
`72\pi\ in^(2)`

Explanation:

we know that

The lateral area of a cylinder ( curved area of the vase) is equal to

`LA=2\pi rh`

we have

`r=6/2=3\ in` ------> the radius is half the diameter

`h=12\ in`

substitute the values

`LA=2\pi (3)(12)=72\pi\ in^(2)` -----> exact value

assume

`\pi=3.14`

`72(3.14)=226.08\ in^(2)` ----> approximate value
