Question

find the radius of a cone if its curved surface area is 352cm² and slant height is 28cm.​

Answer 1

Given Height = 16 cm Curved surface area = 352 cm² We know that, Curved Surface area of a cylinder = 2лrh 2лrh = 352 22 2 x xrx 16 352 7

⇒ r = 352 x 1 7 1 X X 2 22 16 7 == 2 = 3.5 cm Hence, radius of the cylinder is 3.5 cm.
