Answer:
______
Given, radius of cylindrical coin, r = 0.8 m = 80 cm
Height of coin = thickness = 0.4m = 40 cm
Height of cylinder h = 10 cm
Radius of the cylinder, r' = 8 cm
A/Q,
No. Of coins * Volume of 1 coin = Volume of Cylinder
=> N * 22/7 * 80* 80* 40 = 22/7 * 8 *8*10
= > N * 5632/7 = 14080/7
=> N = 14080/5632 = 2.5
Therefore, Answer is 2.5.
