Step-by-step explanation:
Info of coin:
Radius: 1.5 / 2 cm
=15/20 cm ———— 3/4 cm
The thickness is the height that is 0.2 cm
2/10 or 1/5 cm
Volume of coin— pi x r^2 x h
22/7 x 3/4 x 3/4 x 1/5 = 198/560
Volume of the cylinder = pi x r^2 x h
22/7 x 3 x 3 x 16 = 3168/7
Let the number of coins be y
Therefore, volume of coin x Y = volume of cylinder.
198/560 x Y = 3168/7
Y = 3168/7 x 560/198
Y = 1280
