Lean body weight is a component of body composition by subtracting fat weight from body weight
We can use the formula for the area of circle which is A = πr².
Find the diameter by dividing 7 and 2 which you get 3.5.
Substitute with the given values; A = (3.14)(3.5)².
Solve for the exponent; A = (3.14)(12.25).
Multiply; A = 38.465.
~Good luck
