Find the ratio between the total surface area of the cylinder to its curved surface area,given that its height and radius are 7.5 cm and 3.5 cm.
Given radius = 3.5cm
height = 7.5cm
Curved Surface Area of cylinder = 2πrh
= 2*22/7 *3.5 *7.5
= 165 cm2
Total Surface Area of cylinder = 2πr(h+r)
= 2 *22/7 * 3.5(3.5+7.5)
= 242cm2
Ratio of Total Surface Area of cylinder : Ratio of Curved Surface Area of cylinder
= 242 : 165
= 22 :15
