Blood flows in an aorta of radius8.0mm at34cm/s

.(a) Calculate the volume flow rate in liters per minute.

 L/min?

(b) Although the cross-sectional area of a capillary is much smaller than that of the aorta, there are many capillaries, so their total cross-sectional area is much larger. If all the blood from the aorta flows into the capillaries and the speed of flow through the capillaries is1.10mm/s, calculate the total cross-sectional area of the capillaries.
