Question

What is the surface area of the cylinder?
2 mm
10 mm
Use n = 3.14 and write your answer as a decimal rounded to the nearest tenth.
about
square millimeters

Answer 1

Surface area = 2πr^2 + 2πrh
r = radius of the cylinder
h = height of the cylinder

Given:
r = 2 mm
h = 10 mm

Surface area = 2 * 3.14 * (2)^2 + 2 * 3.14 * (2)(10)
Surface area ≈ 25.12 + 125.6
Surface area ≈ 150.72 square millimeters

Therefore, the surface area of the cylinder is about 150.7 square millimeters.
