Answer: about 450.52
Use Pythagorean Theorem to find the diameter of the circle. Divide the diameter by 2 to find the radius, and solve for the area of the circle (πr^2). Then, solve for the area of the triangle (bh/2). Subtract the area of the triangle from the area of the circle.

Learn this...it helps
HOY = horizontal line, 0 slope, represented by x = a number
VUX = vertical line, undefined slope, represented by x = a number
undefined slope -- so its a vertical line
(5,-8)...remember, vertical lines are represented by x = a number....so we can say x = (now, what is the number for x in ur set of points ? it is 5...so ur equation is x = 5. it does not matter what value y is, x is ALWAYS gonna be 5
