Assuming you mean a circle.
Then use the equation.
C = pi*d
'pi' is the constant of direct proportion of circles, and has the approximate value os 3.1416
Hence
C = 3.1416 x 7ft = 21.9912 ft.
The circumference will be 7*pi feet
Circumference of the circle = 7*pi feet
There is a problem here. A circle with a 7-foot diameter has a circumference of 21.99 feet, not 10 feet.If the circumference is 10 feet, that would make the diameter 3.183 feet.
If its circumference is 21.98 feet then its diameter is 21.98/pi = 7 feet rounded up.
If the circumference of a circle is 20 feet the diameter is: 6.366 feet (circumference divided by pi = diameter).
The circumference will be 7*pi feet
Circumference of the circle = 7*pi feet
There is a problem here. A circle with a 7-foot diameter has a circumference of 21.99 feet, not 10 feet.If the circumference is 10 feet, that would make the diameter 3.183 feet.
The circumference of a 7 feet diameter circle is: about 21.99 feet.You can easily to this calculation for other circles by multiplying the diameter by Pi (about 3.1416). The result is the circle's diameter.
The circumference of a 7-foot diameter circle using 3.14 for Pi is: 21.98 feet (diameter x Pi = circumference).
A circle with a 7 foot diameter has a circumference of 22 feet (approx).
If its circumference is 21.98 feet then its diameter is 21.98/pi = 7 feet rounded up.
7 feet 5 inches = 89 inches circumference = 89*pi inches
The circumference of a circle with a diameter of 20 feet is: 62.83 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).
If the circumference of a circle is 20 feet the diameter is: 6.366 feet (circumference divided by pi = diameter).
