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
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.
4 is a number. It does not have a centre, not a radius.
The distance from the center of a circle to any point on the circle is called the radius of the circle. The radius is a line segment that starts at the center of the circle and ends at any point on the circle. It is always a straight line and is always perpendicular to the circumference of the circle. The radius is half the diameter of the circle, which is the distance across the circle through the center. The diameter of a circle is always twice the length of the radius.
