Question 835937
Gold in the form of solid cylinders will be molded into solid blocks.
 Each cylinder has a diameter of 6.19 cm and a height of 6 cm.
 Each solid block will have a volume of 360 cm3.
 How many cylinders of gold will it take to mold one block of gold?
:
c = no. of cylinders to make one block with a vol of 360 cm
c = {{{360/(CylinderVol)}}}
c = {{{360/(pi*r^2*h)}}}
r = 6.19/2 = 3.095
h = 6
c = {{{360/(pi*3.095^2*6)}}} = 1.99379 ~ 2 cylinders required
