Question

Use the net to find the surface area of the cylinder.

Give your answer in terms of n.

102n yd2

120n yd2

36n yd2

84n yd2

Answer 1

the diameter is 6 so the radius must be 3
height is 14

surface area = 2πrh+2πr^2

Answer 2

so i just plug in the numbers now

Answer 3

yes, make sure to leave pi alone (don't convert to decimals, just plug in the numbers and stick pi on at the end)

Answer 4

how would i do that

Answer 5

replace "r" with 3, "h" with 14

Answer 6

2πrh+2πr^2 = 2(3)(14) + 2(3)(3) and then write pi at the end

Answer 7

okay I understand now

Answer 8

102

Answer 9

good, so 102 pi yd^2 is your answer
