A bowl has the shape of a hemisphere whose diameter is 14 centimeters. By itself, the bowl weights 350 grams. If it is completely filled with liquid that weights 1.25 grams per cubic centimeter, then what is the total weight of the bowl and liquid?

1) 898

2) 1248

3) 1796

4) 2146

To find the diam. of the hemisphere, find the vol. of a sphere of radius 7 cm and then divide that by 2:

V/2 = (1/2) (4/3) (pi) (7 cm) ^3 = vol of hemisphere.

To find the weight of the liquid that fills the hemisphere, mult. this volume by the conversion factor 1.25 grams / cubic centimeter.

To this result, add the weight of the bowl (350 grams). Then you'll have your answer.
