Question

12 The end paint of diameter of circle are(2,4)
and (-3,-1). The radius of cicle is​

Answer 1

Answer:

End points of the diameter : (2,4) and (-3,-1)

Therefore, the distance between the points = length of the diameter

= 2* length of the radius

Length of diameter:

= $\sqrt{(2-(-3))^2 + (4 - (-1))^2}$

= $\sqrt{(5)^2 + (5)^2}$

= $\sqrt{50}$

= $5\sqrt{2}$

Therefore, the radius = diameter/2

=> $5\sqrt{2}$ / 2

=> 2.5 * 1.732

=> 4.33 units
