What's wrong?

Question

from math import pi
def roundarea(radius):
if radius>0:
return sqr(radius) * pi
else:
return "Wrong!"

rndr = roundarea
x = input ("Radius is: ")
print(rndr(x))

Answer 1

Try this:

import math
def roundarea(radius):
if radius>0:
return math.sqrt(radius) * math.pi
else:
return "Wrong!"

x = int(input ("Radius is: "))
print(roundarea(x))

You have used a function named sqr() which was not defined. So I used the math module in Python to calculate the square-root and to get the Pi values. And I also converted the input to an integer using the int() function.

Answer 2

The same

Answer 3

what's the error?

Answer 4

Radius is: print(roundarea(x)) in the end

Answer 5

from math import pi
def roundarea(radius):
if radius>0:
return sqr(radius) * pi
else:
return "Wrong!"

x = input ("Radius is: " )
print(roundarea(x))
Result:
Radius is: print(roundarea(x))

Answer 6

Not sqrt, sqr
And it's wrong too
