3. Find the distance between (5, 6) <strong>and</strong> (-5, -6).<br />
Let A( 5,6) <strong>and</strong> B(-5,-6)<br />
x1 = …., x2 = …..<br />
y1 = …., y2 = …..<br />
Distance (AB) = ……………………..<br />
= …………………<br />
= …………….. units<br />
4. Find the distance between the points (–2, –3) <strong>and</strong> (–4, 4).<br />
Let A(-2,-3) <strong>and</strong> B(-4,4)<br />
x1 = ……..., x2 = ……....<br />
y1 = ……..., y2 = ……...<br />
Distance (AB) = ……………………..<br />
= …………………<br />
= …………….. Units<br />
5. Find the radius of a circle, given that the centre is at (2, –3) <strong>and</strong> the point<br />
(–1, –2) lies on the circle.<br />
Let the radius of the circle be r units<br />
using distance formula we have<br />
x1 = ………., x2 = ………<br />
y1 = ……….., y2 = ………<br />
OA = ………………………<br />
OA = …………… = ………….. units<br />
