Answer» 7cmStep-by-step explanation: Breadth of one PLATE= 1/2cmheight of the cylinder= 96*1/2cm= 48cmVolume of a right CIRCULAR cylinder= πr²h7392cm³= πr²h22/7*r²*48cm= 7392cm³22/7*r²= 154cm²22*r²= 1078cm²r²= 49cm²r= 7cmRadius of cylinder= RADIUS of circle(all CIRCLES here are equal)so, radius of each circular plate is 7cm |
