Answer:
Calculate the volume of a coin of radius 1.5cm and 0.2cm
ANSWER:-
Each one of those coins is also a cylinder (just a very very short one), and its volume is V = πr²h = π(.75)²(.2) = 9π/80 cm³
The right circular cylinder has volume (V) = π(2.25)²(10) = 405π/8 cm³.
Divide the larger cylinder's volume by the volume of each coin
= (405π/8) / (9π/80)
= 450 coins
