Start by finding the distance between the 2 points: (2, 5) and (10, 20). This will give you the radius.

here you have two points (2, 5) and (10,20) first find the distance between these points to find the radius then use standard circle equation

(x+2)^2+(y+5)^2=17^2 would be your solution.

You are given the center point which was (2, 5). The question also stated that you want it to cross through a specific point being (10, 20). Therefore, you need to find the distance between the center and where the circle will cross. dw:1353438876550:dw

So by finding the distance between the center point and the outside point, you'll find the radius.
