Answer:
375
Step-by-step explanation:
Given:
Radius of coin(r)=2.4/2
=1.2cm
Height of coin(h)=2mm
=0.2cm
Radius of cylinder(R)=6/2
=3cm
Height of cylinder (H)=12cm
Solution-
No. of coins=volume of cylinder/ volume of coin
=pi*R^2*H/pi*r^2*h
=R^2*H/r^2*h
=3^2*12/1.2^2*0.2
=9*12/1.44*0.2
=108/0.288
=108000/288
=375
