Practice finding the volume of a cylinder. The formula is Volume = π × r² × height.
Multiply the area of the circular base by the height: V = π × r² × h. With a radius of 3 and a height of 10 (π ≈ 3.14), the volume is 3.14 × 9 × 10 = 282.6 cubic units.
Cubles kits are geometry in your hands: nets, faces, edges and vertices that fold and click into a poseable 3D character. No scissors, no glue, about 15 minutes.
