Multiple choice

If the radius and the height of a cylinder respectively are 25 cm and 42 cm, then its lateral surface area is:

  1. 1,960 cm2

  2. 660 cm2

  3. 6,600 cm2

  4. 6,000 cm2

  5. NA

C Correct answer
Explanation

Lateral surface area of a cylinder = 2 * pi * r * h. Using pi = 22/7, r = 25, h = 42. Area = 2 * (22/7) * 25 * 42 = 2 * 22 * 25 * 6 = 44 * 150 = 6600.

AI explanation

The lateral surface area of a cylinder is calculated using the formula 2*pi*r*h. Substituting the given radius of 25 cm and height of 42 cm gives 2 * (22/7) * 25 * 42. This simplifies to 2 * 22 * 25 * 6, resulting in a lateral surface area of 6,600 cm2.
