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?

Question

campbell_st · Answer

start by finding the radius of the cylinder. 

then volume of a cylinder is 

$$V = \pi \times  r^2\times h$$

r = radius and h = height

substitute and find the volume of gold in the cylinder. 

the last part is the number of cylinders. 

it will be 

volume of the block divided by volume of a cylinder. 

hope this helps
