The volume of a sphere with radius r is 4/3πr³. Write a Python program to find the volume of spheres with radius 7 cm, 12 cm, 16 cm, respectively.

Program:
#defining three different radius using variables r1, r2, r3
r1 = 7
r2 = 12
r3 = 16
#calculating the volume using the formula
volume1 = (4/3*22/7*r1**3)
volume2 = (4/3*22/7*r2**3)
volume3 = (4/3*22/7*r3**3)

#printing the volume after using the round function to two decimal place for better readability

print("When the radius is",r1,"cm, the volume of the sphere will be", round(volume1,2),"cc")
print("When the radius is",r2,"cm, the volume of the sphere will be", round(volume2,2),"cc")
print("When the radius is",r3,"cm, the volume of the sphere will be", round(volume3,2),"cc")


OUTPUT:
When the radius is 7 cm, the volume of the sphere will be 1437.33 cc
When the radius is 12 cm, the volume of the sphere will be 7241.14 cc
When the radius is 16 cm, the volume of the sphere will be 17164.19 cc
