Find the area of a circle with center (2,3) that passes through (2,7). use 3.14 for pie

Step-by-step explanation:

A circe that passes through a point means that is a point on the edge, whch also means the distance from the center to that point is the radius, so we just hae to find the distance for that.

To find the distance between the two points you use the formula

sqrt((x2 - x1)^2 + (y2 - y1)^2) where the xs are each of the x values of the two points  and the ys are the y values of the two points.  So we  just plug those in.

sqrt((x2 - x1)^2 + (y2 - y1)^2)

sqrt((2 - 2)^2 + (7 - 3)^2)

sqrt(0^2 + 4^2)

sqrt(4^2)

4

If you graphed the two points it would have been super easy to see the distance since the x value doesn't change.  But it's good to know this method since you can find the distance between any two points.  Anyway, the radius is 4.

Now, the area of a circle is pi*r^2, so you jsut plug in.

pi*4^2

3.14*16
