Question

Gold in the form of solid cylinders will be molded into solid blocks. Each cylinder has a diameter of 6.18 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?

Answer 1

The formula for the volume of a cylinder is
V = pi*h*(d/2)^2
The volume of one cylinder has V = 3.14159*6*(6.18/2)^2 =179.98 cm3
To get the number of cylinder, 360/179.98 = 2 cylinders
