Which equation is the equation of a circle with a diameter of 10 cm and a center at (-3,6) ? a. (x - 3)^2 + (y + 6)^2 = 100b. (x + 3)^2 + (y - 6)^2 = 100c. (x - 3)^2 + (y + 6)^2 = 25d. (x + 3)^2 + (y - 6)^2 = 25

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
