Blood flows in an aorta of radius 4.62mm at 35.0cm/s. Calculate the volume flow rate.

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 is 1.10mm/s, calculate the total cross-sectional area of the capillaries.
