30 feet Assuming you are asking about a circle, then the area is Pixr^2 where r is the radius. Then if 700 were approximately equal to Pixr^2 then 700/3.14159 would be approximately equal to the radius squared. This is about 223 (222.8 is a little better approx) Now the square root of 223 is approximately 15 so the diameter is about 30 feet.
If the radius is 8 feet then the diameter will be 16 feet.
A circle with a circumference of 60 feet has a diameter of: 19.1 feet
If the radius (not raduis) is 25 feet then the diameter is 50 feet.
A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
The circumference of a circle with a diameter of 50 feet is about 157.1 feet. (diameter x Pi = circumference).
If the radius is 5 feet then the diameter is 10 feet
If the radius is 8 feet then the diameter will be 16 feet.
A circle with a circumference of 60 feet has a diameter of: 19.1 feet
If the radius (not raduis) is 25 feet then the diameter is 50 feet.
If a circle has a diameter of 21 feet the circumference is: 65.97 feet (diameter x Pi = circumference).
The diameter of a circle with a 48 feet circumference is: 15.28 feet (circumference divided by Pi = diameter).
The circumference of a circle with a diameter of nine feet is: 28.27 feet (diameter x Pi = circumference).
Radius is half the diameter, so a radius of 50 feet the diameter will be 100 feet.
A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
The circumference of a circle with a diameter of 50 feet is about 157.1 feet. (diameter x Pi = circumference).
If the circumference of a circle is 20 feet the diameter is: 6.366 feet (circumference divided by pi = diameter).
The circumference of a circle with a diameter of 20 feet is: 62.83 feet (diameter x Pi = circumference).
