Question

the endpoints of a diameter of a circle are 3,-4 and -5,2 the radius of the circle is​

Answer 1

Answer:

5 units

Step-by-step explanation:

If A(3, - 4) and B(- 5, 2) are endpoints of a diameter of a circle, then

$d=\sqrt{(x_{1}-x_{2})^2+(y_{1}-y_{2})^2} =\sqrt{(3+5)^2+(-4-2)^2} =\sqrt{100} =10$

radius of a circle is $r=\frac{d}{2} = 5 units$
