Question

(0,0) is the centre of circle.its radius is 17. then point A(8,15) is the interior of circle . state true or false and why?​

Answer 1

Step-by-step explanation:

Distance of the point from centre is given by

$d = \sqrt{ {(0 - 8)}^{2} + (0 - 15) ^{2} }$

$d = \sqrt{ {8}^{2} + {15}^{2} } = \sqrt{64 + 225} \\ = \sqrt{289} = 17$

Since the distance is equal to the radius, the point lies on the circle and not interior of the circle
