Question

Determine the surface area of the cylinder. (Use π = 3.14)

net of a cylinder where radius of base is labeled 5 inches and a rectangle with a height labeled 4 inches

157 in2
219.8 in2
282.6 in2
314 in2

Answer 1

282.6in^2

Explanation:

Surface area of a cylinder = 2πrh+2πr^2

plugging in r=5 and h=4 gives

2π20+2π25

40π+50π = 90π

90*3.14=282.6in^2
