Centre is 169 and Radius is 84.5
If x^2 plus y^2 = 169 then the center of the circle is at (0, 0) and its radius is the square root of 169 which is 13
Radius = 7.334464586 units Check: pi*7.3344645862 = 169 square units
The radius is the line from the center of a circle to its circumference.
radius
# Find the center of the circle # Draw the line of the radius from the center to the circumference # Finish
The radius of the center circle is 9.15 mts. (10yds)
Radius is the center of the circle to the edge.
pi*radius2 = 169*pi Divide both sides by pi then square root both sides to find the radius: radius = 13 and 2*13 = a diameter of 26 cm
4 is a number. It does not have a centre, not a radius.
It is x^2 + y^2 = 169
Use the formula for the circle: area = pi x radius squared. Replace the area, and solve for the radius. Multiply the radius by 2 to get the diameter.
The radius of curvature is the distance from the center of a curved surface or lens to a point on the surface, while the center of curvature is the point at the center of the sphere of which the curved surface is a part. In other words, the radius of curvature is the length of the line segment from the center to the surface, while the center of curvature is the actual point.
