Some forms of cardiovascular disease involve the buildup of plaque on the inside walls of blood vessels. The buildup can put add

ed 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.
