Given:

Given that a circle, with two points


\begin{gathered} A(5,0) \\ B(3,4) \end{gathered}

Required:

To find, circumference, arc length, area of the circle and area of the shaded region.

Step-by-step explanation:

The radius of the given circle is 5 unit.

The circumference is,


\begin{gathered} C=2\pi r \\ =2*\pi*5 \\ =10\pi \end{gathered}

Now the area of the entire circle is,


\begin{gathered} A=\pi r^2 \\ =\pi*5^2 \\ =25\pi \end{gathered}
