Question

71. What is the radius of the circle with equation (x +5)2 + ( y - 3)2 = 144? 72 What is the radius of the circle with equation ( x -2)2 + 3 + ( y + 1)2 = 7? 73. Circle A has equation ( x + 5)2 + y2= 169. The diameter of circle B is one fourth as long as thediameter of circle A. What is the radius of circle B? 74. What is the distance between T (9, -5) and the center ofthe circle with equation (x - 6)2 + ( y + 1)2=10 ? 75. Find the distance between the centers of the circles withequations (x - 5)2 + ( y - 1)2 = 16 and (x +1)2 + (y - 9)2 = 49 76. What is the area of the circle whose equation is ( x +1)2 + ( y + 1)2 = 1? Round your answer to the nearest hundredth 71.

Explanation / Answer

(x-h)2 + (y-k)2 = radius2 71) 12 (square root of 144 is 12) 72) 2 (move the 3 to the other sides then the square rootof 4 is 2) 73) 3.25 (Hint Circle A R=13, D=2R, CB D=1/4CA D) You can find the rest :) (If not just PM me) 71) 12 (square root of 144 is 12) 72) 2 (move the 3 to the other sides then the square rootof 4 is 2) 73) 3.25 (Hint Circle A R=13, D=2R, CB D=1/4CA D) You can find the rest :) (If not just PM me)
