Find the surface area of the cylinder. use 3.14 for pi and round your answer to the nearest tenth.

875.4 cm²

Step-by-step explanation:

The surface area is composed of the 2 circular ends and the curved surface.

Area of ends = 2 × πr² ← r is the radius

here diameter = 13.6, so r = 13.6 ÷ 2 = 6.8

A = 2 × 3.14 × 6.8² ≈ 290.39 cm²

area of curved surface = 2πrh ( r is the radius and h the height )

here h = 13.7, thus

Area = 2 × 3.14 × 6.8 × 13.7 ≈ 585.04 cm²

Surface area = 290.39 + 585.04 = 875.4 cm² ( to nearest tenth )
