Math Grade 8 Quiz Volumes of Cones, Cylinders, and Spheres – 8.G.C.9

The volume of a three-dimensional object is the amount of space it occupies. For cones, cylinders, and spheres, specific formulas allow us to calculate their volumes:

Cylinder: V = πr^2h

Cone: V = (1/3)πr^2h

Sphere: V = (4/3)πr^3


V = Volume

r = radius of the base (for cylinder and cone) or the sphere

h = height of the cylinder or cone
