8. Find the number of coins 1.5 cm in diameter and
0.2 cm thick to be melted to form a right circular
cylinder of height 16 cm and diameter 6 cm.​

Answer 1

Answer:

Step-by-step explanation:

As the coins are in the form of thin cylinder

Volume of each coin = π×(0.75)²×0.2 =0.1125π cm³

Volume of melted cylinder = π× (2.25)²× 10 = 50.625π cm³

number of coin required = (volume of melted cylinder)/(volume of each coin)

                                = 50.625π/0.1125π = 450 coins
