Question 258478: Blood flow is partially controlled by the cross-sectional area of the blood vessel through which the blood is traveling. Blood vessel B has a radius of 1 times 10−4mm and blood vessel D has a radius of 5 times 10−5mm. Let r1 be the radius of B and r2 be the radius of D. Find the ratio of r1 to r2. What does the ratio tell you? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Blood flow is partially controlled by the cross-sectional area of the blood vessel through which the blood is traveling. Blood vessel B has a radius of 1 times 10−4mm and blood vessel D has a radius of 5 times 10−5mm. Let r1 be the radius of B and r2 be the radius of D. Find the ratio of r1 to r2. What does the ratio tell you?
------
r1:r2 = r1/r2 = (1x10^(-4))/(5x10^-5)
= (1/5)x10
= 0.2x10
= 2
---------------
r1:r2 = 2:1
----------------
r1 is twice the radius of r2
