EXPLANATION
The circumference of a circle is calculated using the formula:
From the question, the radius of the circle is 10 inches.
We substitute the radius into the formula to get:
Let us multiply out to get:
The question required that we leave the answer in terms of π.
The correct choice is C.
The Fundamental Theorem of Calculus regarding geometry states that
Where F is the indefinite integral of
The first step is to integrate
Then substitute the value of
and 
into 
![[2 (b)^{2}]-[2 (1)^{2}] = 240](https://tex.z-dn.net/?f=%5B2%20%28b%29%5E%7B2%7D%5D-%5B2%20%281%29%5E%7B2%7D%5D%20%3D%20240%20)
Hence the limit of the area under is between and
