Radius = 21 cm
Height = 3m =300 cm
Curved surface area of cylinder = 2 x pi x r x h
= 2 x 22/7 x 21 x 300 = 39600 m square
Height = 3m =300 cm
Curved surface area of cylinder = 2 x pi x r x h
= 2 x 22/7 x 21 x 300 = 39600 m square

Curved surface area = 2 pi r h
= 2 multiply 22/7 multiply 21 multiply 300
= 39600 cm^2
Volume of pillar = pi r^2 h
= 22/7 multiply 21 multiply 21 multiply 300
= 415800 cm^3
= 2 multiply 22/7 multiply 21 multiply 300
= 39600 cm^2
Volume of pillar = pi r^2 h
= 22/7 multiply 21 multiply 21 multiply 300
= 415800 cm^3
