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 />
