Question

A cylinder has a diameter of 40 feet and a height of 32 feet. What is the surface area of the cylinder? Express the answer in terms of

Answer 1

Answer:above me is correct C

Explanation:

Answer 2

`2080\pi \text{ square ft}`

Explanation:

Since, the surface area of a cylinder is,

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

Where, r is radius,

h is the height,

Here,

The diameter of the cylinder = 40 ft,

So, the radius of the cylinder, r =
`(40)/(2)=20\text{ ft}`

And, h = 32 ft

Thus, the surface area of the cylinder is,

`A=2\pi (20)(20+32)`

`=40\pi (52)`

`=2080\pi \text{ square ft}`
