yo wazzup so can you guys help me with this one problem? Thanks a bunch!
Draw a circle whose center is at (1,2) so that the point (1,5) is a point on the circle. What is the circumference of the circle.
I don't get those problems!
Note that both points are on the line x=1, and are 3 units apart. So, the radius of the circle is r=3.
Now, C = 2pi*r
