So, point (–2.5, 3.5) lies inside the circle. 2 Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Cancel the best answer You must login to add an answer.

Given equation of the circle isx² + y² = 25⇒(x-0)² + (y-0)² = 5²As we know that the equation of the circle is(x-h)² + (y-k)² = r²So, centre = (h,k) = (0,0)and radius = r = 5Distance between point (-2.5, 3.5) and centre (0,0) is√(-2.5-0)²+(3.5-0)²= √6.25 + 12.25= √18.5= 4.3 (approx.) < 5Since the distance between point (–2.5, 3.5) and centre (0, 0) of the circle is less than the radius of the circle.So, point (–2.5, 3.5) lies inside the circle.
