If (2, -7) and (8, 15) are the endpoints of a diameter of a circle, what is the equation of the circle?
A)
(x + 5)2 + (y – 4)2 = 60
(x - 5)2 – (y – 4)2 = 80
9
(x - 5)2 – (y + 4)2 = 110
D)
(x - 5)2 + (y – 4)2 = 130

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

b, i believe, but not sure.

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
