Answer:
875.4 cm²
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 )
