Question

If the center of a circle is C(3,5) and a point P(-3,5) lies on the circle, find its radius.​

Answer 1

Answer:

Radius is 6cm

Explanation:

Radius of this circle will be equal to the distance between P and C

Using distance formula,

PC=root of ((3-(-3))^2 + (5-5)^2)

PC = root of 36 =6

Therefore., radius of the circle is 6 units
