In [1]: import math In [2]: math.sqrt(4) Out[2]: 2.0 In this code, on input line 1 you imported the math library that is built-in to Python. Then, input line 2 computes the square root of 4 using the square root function from within the math library. The math.sqrt() line...
You can solve this equation using the Python square root function: Python >>>a=27>>>b=39>>>math.sqrt(a**2+b**2)47.43416490252569 So, Nadal must run about 47.4 feet (14.5 meters) in order to reach the ball and save the point. ...
