Question

find the radius of the circle whose endpoints of diameter are (-4, 1), (2, -3).

Answer 1

let we will find distance between the two points
distance=diameter
(x1=-4,y1=1)=a
(x2=2,y2=-3)=b
distance of ab=diameter

Answer 2

The radius of circle is 3.6 cm

Step-by-step explanation:

Endpoints of diameter :

$(x_1,y_1)=(-4,1)$

$(x_2,y_2)=(2,-3)$

Length of diameter = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

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

Length of diameter =7.2

Radius of circle =$\frac{Diameter}{2}=\frac{7.2}{2}=3.6 cm$

Hence The radius of circle is 3.6 cm
