Asphere with a radius of 6 cm has the same volume as a cylinder with a height of 4.5 cm. what is the radius of the cylinder

Answer;

radius of the cylinder = 8 cm

Explanation;

          4/3πR³= πr²H, cancelling out π, we get;

            4/3R³ = r²H

            4/3 × 6³ =r² × 4.5

            4/3 × 216 = 4.5 r²

              4.5 r² = 288

                 r² = 64

                 r = √ 64

                = 8 cm

The radius of the cylinder is thus, 8 cm
