Four times the area of the curved surface of acylinder is equal to 6 t – InterviewSolution

1.	Four times the area of the curved surface of acylinder is equal to 6 times the sum of the areas ofits bases. If its height is 12 cm, find its curvedsurface area
Answer» Curved Surface Area= 2πrh sq.cmArea of the base = πr² sq.cm.Sum area of the base= πr²+πr²= 2πr²sq.cmA.T.Q4(2πrh)= 6×2πr²8πrh=12πr²2h=3r2×12=3rr=8cm.Curved Surface Area=2πrh= 2×22/7×8×12=4224/7= 603.42 sq.cm
