The total number of coins required is 450 coins

Step-by-step explanation:

Radius of a coin = 1.5/2 = 0.75  cm

Radius of cylinder  =4.5/2 = 2.25  cm

No. of coins required=  volume of cylinder/volume of coin

Volume of cylinder = 7 x 22 x 2.25 x 2.25 x 10 x 7

Volume of coin = 22  x 0.75 x 0.75 x 0.2 x 7

= 450 coins

Thus the total number of coins required is 450 coins
