A- 416
B- 72
C- 36
D- 208

D

Step-by-step explanation:

The area of each of the triangles is (1/2)(9)(8).

So the area of all 4 triangles combined is (2)(9)(8)=144.

The area of the square is 8^2 = 64

So the total surface area is 144 + 64 = 208

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
