Some forms of cardiovascular disease involve the buildup of plaque on the inside walls of blood vessels. The buildup can put added stress on the heart and vessels, reducing or preventing blood flow to vital organs of the body.

Imagine that the diagram is a circular cross section of a blood vessel. What is the area of the inside of the blood vessel (i. e., the pink part) in square units? Round your answer to the nearest tenth. The equation for the area of a circle is A = πr2, where A is area, π ≈ 3.14, and r is the radius. Recall that the radius is half of the diameter.

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

the answer is : )

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
