# Volume Of A Sphere Or Hemisphere (Word Problems) Worksheet

## 7 problems   In 8th Grade, students learn how to find the volume of 3D figures such as spheres, and hemispheres. A sphere is a ball-shaped figure and a hemisphere is a bowl-shaped figure. The volume of a sphere is V = 4/3 πr^3, where r is the radius of the sphere and the volume of the hemisphere is half of the volume of a sphere.

Math teachers can provide “Volume of a sphere or hemisphere (word problems) worksheet” to their students. This worksheet includes a variety of word problems that require students to calculate the volume of sphere-shaped or hemisphere-shaped objects where the radius is given.

Volume
8.G.C.9

Students need to substitute the value of the radius in the formula V = 4/3 πr^3 to find the volume of the sphere. For example, Ammi bought a snow globe during a recent vacation to New York City. The globe is a hemisphere with a diameter of 3 inches.

If the radius of a sphere is 3 in, then the formula V = 4/3 πr^3 becomes V= 4/3π(3)^3. After simplifications, the final value can be V=36π cubic inches. The volume of the hemisphere is half of the volume of sphere, therefore the volume of Ammi’s snow globe is 18π cubic inches.
