Which point is on the circle centered at the origin with a radius of 5 units? distance formula: (2,4.79 ) (2,4.58 ) (2, 1) (2, 3)

(2,4.58) is on the circle. The distance from original to point (x,y) is \sqrt(x^2+y^2). Since (x,y) is on the circle centered at the origin with radius 5, x^2+y^2=5^2=25. Among the choices given, only 2^2+4.58^2=5^2, so point (2, 4.58) is on the circle.

The answer is "a"radius = 12.7 unitsdiameter = radius × 212.7 units × 2 = 25.4 units
