The equation of a circle is x^2 + y^2= 42.25 Find the radius of the circle.

radius = 6.5

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( where r is the radius )

x² + y² = 42.25 ← is in this form

with r² = 42.25 ( take the square root of both sides )

r = = 6.5
