Question 5 Mensuration Exercise 17.1

An electric geyser is cylindrical in shape, having a diameter of 35 cm and height 1.2m. Neglecting the thickness of its walls, calculate its capacity in litres.

Answer:

Solution:

The capacity of a cylinder, which determines how much material it can carry, is determined by the cylinder's volume.

Capacity of the cylinder = π r2h

= (22/7)×17.52×120

= 115500 cm3

= 115.5 litres [∵1000 cm3 = 1 litre]

Hence the outer lateral surface area and the capacity of the cylinder is 13200 cm2 **and 115.5 litres respectively.** M L Aggarwal - Understanding ICSE Mathematics - Class 10 chapter Mensuration Question 5 Solution image
