How many spheres of diameter 10cm can fit in a cylindrical jar of radius 15cm and height 20cm?

The answer to your question is 3.38 spheres fit in the jar

Step-by-step explanation:

Data

Sphere diameter = 10 cm

Cylindrical jar

                       radius = 15 cm

                       height = 20 cm

Formula

Volume sphere = 4/3 πr³

Volume cylinder = πr²h

Process

1.-Find the volume of the sphere and the volume of the cylinder

Volume sphere = 4/3π (10)³ = 1333.33π cm³

Volume cylinder = π(15)²(20) = 4500π  cm³

2.- Divide the volume of the cylinder by the volume of the sphere

Number of spheres = 4500 π / 1333.33 π

                                 = 3.38
