Question 1035377: A cylindrical block has a diameter of 25 cm and a height of .25 m. Its made of a metal weighing .01 mg/cubic mm. What is the total weight of the block? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Hi there,
25 centimeters = 250 millimeters
0.25 meters = 250 millimeters
Volume of cylinder = π x radius^2 x height
Volume = π x 125^2 x 250
Volume = 12271846.3 mm^3
Weight = .01 mg/mm^3
Weight = .01 x 12271846.3
Weight = 122718.463 mg
Weight = 122.72 g.
Hope this helps :-)
