The center of the circle is at point (0,6). If the distance between the two points
where the circle intersects the x-axis is 16, what is the area of the circle?
This question had been decided just a few days back. I didn't quiet understand the explanations so reposted it.
Please help.
Help please!

The distance between each intersection point and the centre of the circle is the radius of the circle. Since the two intersection points must be at equal length from the y-axis, the intersection points are (-8, 0) and (8,0).
The distance between one of these points and the centre is = √(8^2+6^2)=√100 = 10 = the radius
Area = πr^2 = 100π.

Hey Deirdre, thanks for your reply, I really appreciate it!
Actually, I misinterpreted the words in the question!
