 Question 187485: I have a geometry question that is on my worksheet for my homework. My worksheet is labeled Distance in Coordinate Geometry. My question is Given circle O with O(3,-4) and radius 5, find 12 points on the circle with integer coordinates. I am stuck. I have been taught the formula for finding the equation of a circle which was tuaght to me like this: EXAMPLE: If the radius of a circle is 16 and the coordinates of the centerpoint are (3,4), then what is the equation? First, you put the x coordinate of the centerpoint into the first set of parantheses adn the y into the second set of parantheses. It should look like this . I hope that this is clear enough. I get stuck here trying to figure out the coordinates of the points on the circle. I think that one of them is (8,-4). Are you suposed to just continue choosing random points to find the points, or is there an easier way? Please help, and thank you so much! Click here to see answer by stanbon(57966)

 Question 191537: Hi. In this question it asks for AB to be found. It is a circle with the center point P. It has a radius of 6 and a chord AB drawn from one point to another. The chord divides the circle into a certain section and it has an arch that on the outside of it it says 120 degrees. The radius is not drawn horizontally, but if it was drawn horizontally it would still be 6 and would seem to bisect the chord and then create a right triangle onto which the Pythagorean theorem could be used to find 1/2 of AB.

 Question 192845: The line PR is tangent to circle T. Circle T has a radius with a length of X that forms a right angle with tangent PR. There is also a line TR which finishes forming a right triangle. Line TR is broken up into two parts. TE and ER. TE is a radius equaling X, and ER equals 16. Tangent PR equals 22. The question says to solve for TE, which equals X. I have already tried the pythagorean theorem but it is not working. Click here to see answer by solver91311(17077)

 Question 194449: Two circles intersect and have a common chord. THe radii of the circles are 13 cm and 15 cm. The distance between their centers is 14 cm. Find the length of their common chord. I already drew the picture. I drew two circles intersecting each other like a venn diagram. Then, i connected the two centers and that equals 14 and drew a line from the center of each circle to an edge of the circle equaling the radius of each circle. Then, I drew a dashed line down the intersection of the two circles in the middle and a perpendicular line shows up with the line connected by the center. What step am I supposed to take from there?
