About this worksheet

What students practice

Students calculate volumes of cylinders, cones, and spheres from radii, diameters, and heights.
Students use volume formulas to find missing dimensions and solve progress-dashboard problems.
Students evaluate volume calculations and explain a cone-height error.

How to use

Use after introducing all three volume formulas. Have students show calculations on separate paper and use exact values in terms of π. Discuss the final debugging task together.

Coding Camp: Progress in 3D

Test the volume calculations behind a project-progress dashboard.

Test the Dashboard

A coding camp team is building a project-progress dashboard with virtual 3D shapes. All dimensions are in virtual centimeters. Keep answers exact in terms of π; enter only the coefficient when π is printed after a blank.

The dashboard uses spherical icons for completed projects. An icon has radius r. Which expression should the program use for its volume?
