1 way is
height = 44cm
circumference = 33cm
radius = ?
C = 2PiR
33cm = 2 X 22/7 X R
33cm = 44/7 X R
R = 33cm X 7/44
R = 5.25 cm
Therefore, the volume of the cylinder would be
Pi R^2 H
= 22/7 X 5.25^2 44cm
= 3811.5 cm3
Another way is
height = 33cm
circumference = 44cm
radius = ?
C = 2PiR
44cm = 2 X 22/7 X R
44cm = 44/7 X R
R = 44cm X 7/44
R = 7cm
Therefore, the volume of the cylinder would be
Pi R^2 H
= 22/7 X 49 X 33
= 5028 cm3
Plz thank me if it was indeed helpful because this question was hard for me too and if there is any mistake plz tell me.
