Find the area of the figure

 Area 89m^2

Step-by-step explanation:

To find the area of the rectangle we multiply

Base * Height = Area

8 * 13 = 104

Now we find the area that isn't shaded

I inference that the base of the triangle is 5m  

5 * 6 = 30

Now divide that by 2

30/2 = 15

Subtract 15 from 104

104 - 15 = 89m^2

And if we compare this to the general equation for a circle:

We see that the radius is and the center would be

Step-by-step explanation:

For this case we have the following equation:

We need to complete the square for x and y like this:

And simplifying we got:

And if we compare this to the general equation for a circle:

We see that the radius is and the center would be
