Question

Longest distance from (12, 17) to the
circle x² + y2 - 6x - 8y - 25=0 is​

Answer 1

Answer:

centre of circle = (3,4)

radius = (50)^1/2

so largest distance = distance between (12, 17) and (3, 4). + radius

$= \sqrt{ {(12 - 3)}^{2} + {(17 - 4)}^{2} } + \sqrt{50} \\ = \sqrt{144 + 169} + \sqrt{50} \\ \sqrt{313} + \sqrt{50}$
