Sol:
Height of the cylinder melt = 45 cm
Diameter of the cylinder = 6 cm
Radius = 3 cm
Diameter of the sphere = 6 cm
Radius = 3 cm
Volume of the cylinder = 22/7 x 3 x 3 x 45
Volume of each sphere = 4/3 x 22/7 x 3 x 3 x 3
Let the number of spheres be 'n'
Volume of all the spheres = Volume of the cylinder
n x 4/3 x 22/7 x 3 x 3 x 3 = 22/7 x 3 x 3 x 45
n x 4/3 x 3 = 45
n = 45/4
n = 11 (approx.)
