Multiple choice

The radius and height of a cylinder are 2 cm and 5 cm respectively. The total surface area of the cylinder will be

  1. 22 cm2

  2. 88 cm2

  3. 24 cm2

  4. 42 cm2

B Correct answer
Explanation

Total surface area of a cylinder = 2 * pi * r * (r + h). Using pi = 22/7, r = 2, h = 5: 2 * (22/7) * 2 * (2 + 5) = 2 * (22/7) * 2 * 7 = 88.

AI explanation

The total surface area of a cylinder is found using the formula 2 times pi times r times (h + r). Substituting the given values gives 2 times 22/7 times 2 times (5 + 2), which equals 88 cm2.
