Can Someone plz help me with the question??

Anestetic [448]

Answer:

$\boxed{x^2+y^2 = 49}$

Step-by-step explanation:

First, we'll find the length of the radius using distance formula and the coordinates (0,0) and (7,0)

Distance Formula = $\sqrt{(x2-x1)^2+(y2-y1)^2}$

R = $\sqrt{(7-0)^2+(0-0)^2}$

R = $\sqrt{7^2}$

Radius = 7 units

Now, Equation of circle:

$(x-a)^2+(y-b)^2 = R^2$

Where (a,b) = (0,0) So, a = 0, b = 0 and R = 7 units

=> $(x-0)^2+(y-0)^2 = (7)^2$

=> $x^2+y^2 = 49$

This is the required equation of the circle.
