Question

four time the area of the curved surface of a cylinder is equal to 6 time. the sum of the area of its base if its height is 14 cm find the curved surface area.​

Answer 1

Answer:

Curved Surface Area= 2πrh sq.cm

Area of the base = πr² sq.cm.

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=2πrh

= 2×22/7×8×12

=4224/7

= 603.42 sq.cm
