Q. Rewrite the following Python code after removing all syntax error(s). Underline the corrections done.
def main():
r = input ('enter any radius:')
A - pi * maths.pow (r, 2)
Print ("Area = "+ a)
Main()
Answer =
Correct code:-
import math
def main():
r = float(input ('Enter any radius:- '))
A = 3.14 * math.pow (r, 2)
print ("Area = ", A)
main()
Output :-
Enter any radius:- 2.6
Area = 21.2264
>>>
Enter any radius:- 4
Area = 50.24
>>>
