If the radius of the base and the slant height of a cone are 13 cm and 35 cm respectively, then what is the curved surface area of the cone?
Show answer & explanation
Correct answer: C
Explanation
The Correct answer is option 3 i.e.1430 cm2
Given that
the radius of the base (r) = 13 cm
and the slant height of a cone (l) = 35 cm
Formula used
CSA of cone = πrl
Calcularion
CSA = (22/7) × 13 × 35 = 1430 cm2
