Question
The radius of the base of a cone is 6 cm, and its slant
height is 10 cm. What is the surface area of the cone?Solution
The surface area of a cone is given by the formula: Surface Area = πr(r + l) Substitute the values: Surface Area = 3.14 × 6 × (6 + 10) = 3.14 × 6 × 16 = 3.14 × 96 = 301.44 cm² Correct Option: c
