Line segments AB and CD bisect cach other at point K(6, 4). Which could be the coordinates of points A, B, C, and D ? A. A(2, 1), B(4,3), C(1, 1), D(5,0)
C. A(3, 2), B(9,6), C(2, 6), D(4,0)
B. 1(-1.3), B(13, 5), ((4.7), D(8,1) D. A(-2, -1), B(10, 13), C(2, 9), D(6, 3)

Some explanation would be greatly appreciated

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
