4 cm radius and height is 10 cm. Find the surface area of the cylinder. Use the formula SA = 2πr^2 + 2πrh. Use 3.14 for π. Round your answer to the nearest tenth.
A. 301.7 cm^2
B. 351.7 cm^2
C. 140.4 cm^2
D. 500 cm^2
First, calculate the surface area using the provided formula:
SA = 2πr^2 + 2πrh
SA = 2 * 3.14 * (4 cm)^2 + 2 * 3.14 * 4 cm * 10 cm
SA = 2 * 3.14 * 16 cm^2 + 2 * 3.14 * 4 cm * 10 cm
SA = 100.48 cm^2 + 251.2 cm^2
SA = 351.68 cm^2
Rounded to the nearest tenth, the surface area of the cylinder is 351.7 cm^2, so the answer is B.
