four times the area of curved surface of a cylinder is equal to 6 times the sum of the area of its two bases if its size is 12 find its curved surface area. About the author Amara

Solution:– Curved Surface Area cylinder = 2πrh Area of the base = πr² Sum area of the base= πr²+πr²= 2πr²sq.cm A.T.Q => 4 (2πrh) = 6 × 2πr² => 8πrh = 12πr² => 2h = 3r => 2 × 12 = 3r r = 8cm. Curved Surface Area cylinder = 2πrh => 2 × 22/7 × 8 × 12 => 4224/7 => 603.42 sq.cm Reply

Solution:–Sum area of the base= πr²+πr²= 2πr²sq.cm

## A.T.Q

## r = 8cm.

Curved Surface Area cylinder = 2πrh
