Question

the endpoints of diameter of a circle are 2, 4 and -3, -1 then find the radius of the circle​

Answer 1

Answer:

1,2,-1.5,-0.5are the answers of above question respectively

Answer 2

The radius of circle is 3.535 unit

Step-by-step explanation:

We are given that the endpoints of diameter of a circle are 2, 4 and -3, -1

$A =(x_1,y_1)= (2,4)$

$B=(x_2,y_2)=(-3,-1)$

We will use distance formula:

Formula : $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute the values in the formula :

$d=\sqrt{(-3-2)^2+(-1-4)^2}=7.07$

So, diameter of circle = 7.07 unit

Radius of circle = $\frac{7.07}{2}=3.535$

Hence The radius of circle is 3.535 unit
