Q7 of 70 Page 20

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.


Given,


Height of cylinder = 7.5 cm


Radius of cylinder = 3.5 cm


So, curved surface area of cylinder = 2πrh = cm2


Total surface area = 2πr(h+r) = cm2


So,
