Question

50 circular plates each if radius 7cm and thickness 0.5 cm are placed one above other to form a right circular cylinder.Find the volume abd total surface area

Answer 1

The height of cylinder formed= 0.5 * 50 = 25cm
Radius = 7 cm
Therefore, volume of the cylinder = pie *r^2*h
= 22/7*49*25
= 3850cm^3
Similarly, you can find total surface area by the formula 2*pie*r(h+r)

Please avoid calculation mistakes
Hope this helps dear!!
