Find the surface area of the cylinder below. Use the approximation 3.14 for pi.
the radius is 5cm and the height is 15cm
A. 1,099 square centimeters
B. 533.8 square centimeters
C. 628 square centimeters
D. 628 centimeters
The surface area of a cylinder can be calculated using the formula:
Surface area = 2πr(r + h)
where r is the radius and h is the height.
Substituting the given values into the formula:
Surface area = 2 × 3.14 × 5(5 + 15)
Surface area = 2 × 3.14 × 5(20)
Surface area = 2 × 3.14 × 100
Surface area = 628 square centimeters
Therefore, the surface area of the cylinder is 628 square centimeters.
The answer is (C) 628 square centimeters.
