  2. 404 cm2

  3. 240 cm2

  4. None of these

A Correct answer
Explanation

Lateral surface area of a cylinder = 2 * pi * r * h. Using pi = 22/7, r = 7, h = 20: 2 * (22/7) * 7 * 20 = 2 * 22 * 20 = 880 cm^2.

AI explanation

Using the formula for the lateral surface area of a right circular cylinder, which is 2 * pi * r * h, we substitute the given radius of 7 cm and height of 20 cm. This gives the expression 2 * (22 / 7) * 7 * 20, which simplifies to 44 * 20. The lateral surface area equals 880 square cm.
