The total surface area of a cylinder whose height is 12.4 cm and radius is 2.1 cm will be ______?
Answer: 191.226 cm^2
Explanation
The total surface area (TSA) of a cylinder is given by:
TSA = 2πr(h + r)
Given:
h = 12.4 cm
r = 2.1 cm
TSA = 2 * π * 2.1 * (12.4 + 2.1)
= 2 * 3.14159 * 2.1 * 14.5
≈ 2 * 3.14159 * 30.45
≈ 191.226
