Question

A solid metal spherical ball of radius 7cm is put inside a cylinder of radius 5cm and height 13cm. if the cylinder is now filled completely with water, find the volume of the water inside the cylinder

Answer 1

Answer:

Step-by-step explanation:

volume of cylinder = πr²h

                                  22/7 × 5×5×13

                                  =7150/7cm²

volume of sphere = 4/3πr³

                                  4/3×22/7×7×7×7

                                  =4312/7cm²

volume of water = volume of cylinder - volume of sphere

                            ⇒ 7150/7 - 4312/7 =2838/7

                             ⇒45.42cm²
