Step-by-step explanation:
Using formula of volume of cylinder= πr²h
Coin Radius= D/2
R = 0.75cm
Height= 0.2cm
π * (0.75)² * 0.2
= π * 0.1125
= 3.14 * 0.1125
= 0.35325cm³
Right circular cylinder
Height= 10cm
Radius= 2.25cm
πr²h
= 3.14 * (2.25)² * 10
= 3.14 * 5.0625 * 10
= 3.14 * 50.625
= 158.9625cm³
No. of coins= 158.96/0.35325
= 450 coins
