Answer: 7cm
Step-by-step explanation: Breadth of one plate= 1/2cm
height of the cylinder= 96*1/2cm
= 48cm
Volume of a right circular cylinder= πr²h
7392cm³= πr²h
22/7*r²*48cm= 7392cm³
22/7*r²= 154cm²
22*r²= 1078cm²
r²= 49cm²
r= 7cm
Radius of cylinder= Radius of circle(all circles here are equal)
so, radius of each circular plate is 7cm

each half =1/2
height of circular=96×1/2
height of circular=48cm
circular cylinder of volume=7392
πr×rh=7392
so solve this equation give answer correct.
