The outer circle of a football field is the border of the field. When the players step outside of the border, the play stops.
x^2+y^2=36
because in 1945, football players squished a football once and decided to name it a circle
The radius of the inner circle is sqrt(9) = 3. The radius of the outer circle is therefore 3*3 = 9. The equation for the outer circle is then x^2 + y^2 = 9^2 = 81. (This is an application of Pythagoras' theorem a^2 + b^2 = c^2 in a right-angled triangle by the way)
If the radius of a circle is twice the diameter. The outer diameter of a circle the size of a circle. 32.25 mm = 1.27 inches
The outer circle of a football field is the border of the field. When the players step outside of the border, the play stops.
The curved outer surface of a circle is the perimeter.
It is the circle's circumference
The inner circle is x2 + y2 = 4. The radius of the inner circle is the square root of 4, which is 2. To find the radius of the outer circle, multiply 2 times 4. The radius of the outer circle is 8. Square 8 (82 or 8 x 8) to find the number to put into the equation of the outer circle. This is 64. The equation for the outer circle is x2 + y2 = 64.
Outer Circle railway line was created in 1890.
Circle rules football was created in 2006.
The radius of a circle is the distance from the centre of the circle to its circumference - which is the outer limit of the circle.
The outer circle of a track is longer this is why the starting line is often set at an angle to the outside of the track.
The outer edge of a circle is called the circumference.

It is greater by 18.8 feet.
