Surface area of cylinders quick check answers

Answer 1

1. The formula for the surface area of a cylinder is SA = 2πrh + 2πr^2, where r is the radius and h is the height of the cylinder.

2. A cylinder has a radius of 5 cm and a height of 10 cm. The surface area would be SA = 2π(5)(10) + 2π(5)^2 = 100π + 50π = 150π cm^2.

3. A cylinder has a radius of 3 inches and a height of 8 inches. The surface area would be SA = 2π(3)(8) + 2π(3)^2 = 96π + 18π = 114π in^2.

4. A cylinder has a radius of 2.5 meters and a height of 6 meters. The surface area would be SA = 2π(2.5)(6) + 2π(2.5)^2 = 60π + 25π = 85π m^2.
