Question
A cone has a base radius of 7 cm and a slant height of
25 cm. Find the total surface area of the cone.Solution
Total surface area of a cone = π * r * (r + l), where r = radius and l = slant height. Given r = 7 cm and l = 25 cm. Total surface area = π * 7 * (7 + 25) = 22 * 32 = 704 cm². = 704 cm². Answer: d) 704 cm².
