Question

The radius of circle with centre O(2, –3) and passing through point A(5, 7) is
(1) 109 units
(2) 109 units
(3) 53 units
(4) 53 units

Answer 1

Answer:

√ 109  units

Step-by-step explanation:

We need to find The radius of circle with centre O(2, –3) and passing through point A(5, 7)

Radius of circle is distance between the center of circle and any point on circle

Radius of Circle = Length of OA

Length of OA  = √(5 - 2)² + (7 -(-3))²  

= √3² + 10²

= √9 + 100

= √ 109

The radius of circle with centre O(2, –3) and passing through point A(5, 7) is

√ 109 units
