Question

NVM it is D

Find the surface area of the cylinder with a radius of 9 inches and a height of 11 inches in terms of pi
a) 198 pi in^2
b) 234 pi in^2
c) 846 pi in^2
d) 360 pi in^2

Answer 1

T.S.A of a cylinder = 2
`\pi`r² + 2
`\pi`rh
=2(9)²
`\pi` + 2(9)(11)
`\pi`
= 162
`\pi` + 198
`\pi`
= 160
`\pi` in²

And yes the Answer is D. 360
`\pi` in²
