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?
so volume of a cylinder=area of top circle times height or pi times radius^2 times height diameter=2 times radius diameter times 1/2=radius 6.19/2=radius=3.095 pi times 3.095^2 times 6=177.077 so volume of cylinder=177.08 volume of gold=360 so x cylinders=1 solid block diviide both sdies by cylinder x=block/cylinder block=360 cylinder=177.08 360/177.08=2.03 so aprox 2.03 cylinders will make one block round down since 0.03 is nigligible the answer is 2
