Question

How many litres of water will a hemispherical bowl of radius 100 cm contain and find its curved surface area?

Answer 1

Radius of hemisphere bowl = 100 cm
Volume of hemisphere = 2*pi*r^3/3
= 2*3.14*100*100*100/3 cm^3
= 2*314*100*100/3*1000 litre
= 314*2*10/3
= 6280/3
= 2093.3 litre

CSA of hemisphere = 2 pi r^2
= 2 * 3.14 * 100*100
= 2* 31400
= 62800 cm^2

Hope it is correct and will help you

Answer 2

CSA of hemisphere=2*22/7*(100)^2
=440000/7
=62857.14 cm cube
