Multiple choice

Write the curved surface area of a right circular cylinder whose radius is $3\ cm$ and height is $5\ cm$.

  1. $30\pi \ {cm}^{2}$
  2. $20\pi \ {cm}^{2}$
  3. $35\pi \ {cm}^{2}$
  4. $40\pi \ {cm}^{2}$

A Correct answer
Explanation

Curved surface area of a cylinder = 2 * pi * r * h. Given r = 3 and h = 5, Area = 2 * pi * 3 * 5 = 30 * pi.

AI explanation

The formula for the curved surface area of a right circular cylinder is 2 * pi * r * h. Substituting the radius r = 3 and the height h = 5 gives 2 * pi * 3 * 5. Multiplying these values gives the result 30 * pi.
