Calculating Volume of sphere

Question

pi=22/7
rad3 = float(input("Enter the radius of the circle: "))
print("\n")
float(print (4/3)* pi *rad3**3)

Im not sure what is wrong with my code

Answer 1

You are printing inside a float cast. That print(4/3) returns a None value, which cannot obviously be multiplied with a float value (pi variable). Maybe you wanted to do print(float((4/3) * pi * rad3 ** 3)) ?

Answer 2

Try this.

pi=22/7
rad = float(input("Enter the radius of the circle: "))
print("\n")
V= 4.0/3.0*pi*rad**3
print ("Volume is", V)
