Looking for a volume of cylinders cones and spheres quiz? Then this Grade 8 quiz on Round Solids: Cylinder, Cone, Sphere Volume asks 10 multiple-choice questions with instant feedback. Ten multiple-choice questions check the volume formulas for cylinders, cones, and spheres, along with scale and missing dimensions. Write the formula before choosing, and read the explanations to see which slip each wrong option stands for.
Standards: 8.G.C.9 · Level: Grade 8
What this Round Solids: Cylinder, Cone, Sphere Volume quiz checks
- Cylinder: V = πr2h.
- Cone: one third of the cylinder that matches its opening and height.
- Sphere: V = (4/3)πr3; a hemisphere holds half of that.
- The radius is half of the diameter, and every formula needs it.
- Capacity is measured in cubic units such as cm3 or ft3.
The 10 questions of the quiz
- Which equation computes how much a can with radius r and height h holds?
- A cone and a cylinder share one radius and one height. How does the cone’s volume compare with the cylinder’s?
- A ball has radius 3 units. What is its volume as an exact value with π?
- How much does the cylinder hold?
- How much does the cone hold?
- A sphere has diameter 10 cm. What is its volume?
- A cylinder has base radius 5 in. and height 10 in. Using 3.14 for π, what is its volume?
- The radius of a cylinder is doubled and the height stays the same. What happens to the volume?
- A bowl is exactly half of a sphere that has radius 6. What volume does it hold?
- A cone has a volume of 100π and radius 5. What is its height?
