I do believe that the answer is 3,500.Hope it helped!
Lymph is the fluid that circulates throughout the lymphatic system. The lymph is formed when the interstitial fluid (the fluid which lies in the interstices of all body tissues) is collected through lymph capillaries
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
