Answer:
you are right
Step-by-step explanation:
you did the math right
well, we can check the units right off the grid.
so, below the x-axis, we have a rectangle, is a 10x3, so it has an area of 10*3.
above the x-axis we have a trapezoid, it has to parallel sides or bases, top is 6 units, bottom base is 10 units, and it has an altitude of 2.
we can just get the area of both, sum them up, and that's the area of the figure.

Answer:
(x -2)^2 + (y-6)^2 = 16
Step-by-step explanation:
The equation of a circle is of the form
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x- 2)^2 + (y-6)^2 = 4^2
(x -2)^2 + (y-6)^2 = 16
