Question 17 Mensuration Exercise 17.1

Find the ratio between the total surface area of a cylinder to its curved surface area given that its height and radius are 7.5 cm and 3.5 cm.



The area of the cylinder is determined by adding the areas of its two circular bases and curved surface.

Given radius of the cylinder, r = 3.5 cm

Height of the cylinder, h = 7.5 cm

Total surface area = 2π r(r+h)

Curved surface area = 2π rh

Ratio of Total surface area to curved surface area = 2π r(r+h)/ 2π rh

= (r+h)/h

= (3.5+7.5)/7.5

= 11/7.5

= 22/15

Hence the required ratio is 22:15. M L Aggarwal - Understanding ICSE Mathematics - Class 10 chapter Mensuration Question 17 Solution image
