The surface area of this cylinder is 2,461.76 square feet. What is the height?
Use pi as 3.14 and round your answer to the nearest hundredth.
The radius is 14 ft

Answer 1

surface area of cylinder = 2 π r h + 2π r²

plug in values of pi, radius and area

2,461.76 = 2× 3.14 × 14 × h + 2× 3.14 × 14 × 14

2,461.76 = 87.92 h + 1,230.88

2,461.76 – 1,230.88 = 87.92h

1,230.88 = 87.92h

1,230.88 ÷ 87.92 = h

h = 14 ft
