Find the curved surface area, if the radius of a cone is 35 m and slant height is 30 m?	Choose the correct choice from the following answers:
A) 1100	B) 2200	C) 3300	D) 4400	E) 5500

Rationale: "cone curved surface area = ï € rl 22 / 7 ã — 35 ã — 30 = 110 ã — 30 = 3300 m ( power 2 ) answer is c ."
Answer: C
