I need help pls is only 1 question

Answer 1

`T = 1300`

Explanation:

Given

`Radius, r = 9\ in`

`Height, h = 14\ in`

See attachment

Required

Determine the total surface area, T

T is calculated using:

`T = 2\pi r(r + h)`

Substitute values for r and h

`T = 2\pi * 9(9 + 14)`

`T = 2\pi * 9(23)`

Remove bracket

`T = 2\pi * 9*23`

`T = 2\pi * 207`

Take
`\pi = 3.14`

So, we have:

`T = 2 * 3.14 * 207`

`T = 1299.96`

`T = 1300` --- approximated.

Hence, the surface area is 1300 square inch
