Step-by-step explanation:
A rectangle piece is overlaped;
Then the length became diameter =22cm
The breath will height = 8 cm
Formula finding volume of cylinder = pi*radius *radius *height
= pi*r square *height
Radius of cylinder = 22cm/2=11cm
The volume of cylinder = pi * r square * height
= (22/7 * 11 square * 8) cm sq
= (22*121*8/7) cm sq
=21296/7
=3042. 28571 cm sq
