For the largest right circular cylinder cut out of a cube of edge r cm, the circular base must fit tightly within the square face of side r cm, giving diameter r cm and radius r/2 cm. The height of the cylinder equals the cube edge, h = r cm. Thus, volume V = π(radius)²(height) = π(r/2)²(r) = (πr³)/Read more

The edge of a cube measures r cm. The largest possible right circular cylinder is cut out of the cube. What do you think is the volume of the cylinder (in cm³)?
For the largest right circular cylinder cut out of a cube of edge r cm, the circular base must fit tightly within the square face of side r cm, giving diameter r cm and radius r/2 cm. The height of the cylinder equals the cube edge, h = r cm. Thus, volume V = π(radius)²(height) = π(r/2)²(r) = (πr³)/Read more
