The total surface area of a cylinder whose height is 12.4 cm and radius is 2.1 cm will be ______?

170.226 cm^2

180.226 cm^2

191.226 cm^2

None of these

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
