Multiple choice

The radius and slant height of a cone are 2 cm and 5 cm, respectively. Find its total surface area.

  1. 22 cm2

  2. 44 cm2

  3. 66 cm2

  4. 88 cm2

B Correct answer
Explanation

Total Surface Area = pi*r*(r+l) = pi * 2 * (2+5) = 14*pi. Using pi=22/7, 14 * 22/7 = 44.

AI explanation

The total surface area of a cone is the sum of its curved surface area and base area, given by the formula pi*r*(l + r). Substituting the given values gives 22/7 * 2 * (5 + 2) = 22/7 * 14. The result is 44 cm2.
