Show that the line 3x-4y-80 is tangent to circle whose center is 7-3 and radius 5. Using Pythagoras we can determine the relationship between the radius of the circle r the center of the circle OX OY and any point on the circle x p y p. GRADE 10 Learning Task 4.
Show that the line 3x-4y-80 is tangent to circle whose center is 7-3 and radius 5.
Uation of a circle with radius 3 and center at 0 0 given by x2 y2 32 Solve the above equation. Recall the equation for a circle with center h k and radius r. So the circle which has a center at the point three negative one and a radius of two units and is therefore the circle representing the equation 𝑥 minus three squared plus 𝑦 plus one squared equals four is circle C.
