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 cm circle is: 21.99 cm(diameter x pi = circumference).
The circumference of a 7-foot diameter circle using 3.14 for Pi is: 21.98 feet (diameter x Pi = circumference).
The circumference of every circle is its diameter multiplied by (pi). For (pi), use 3.142 or 22/7 .
Circumference = 7*pi which is about 22 inches
The circumference of a circle is given by π × diameter. π =3.14159265...... It is approximately 3.14 which, itself, is approximately 22/7. To estimate the circumference of a circle, multiply the diameter by 3 and add the diameter divided by 10 and that division divided by 2; this will give you 3.15 × diameter which is fairly close. Alternatively, multiply the diameter by 22 and divide by 7.
Just multiply the diameter times pi. Pi is approximately 3.1416.
Boundry of circle is called circumference.
pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
Circumference of the circle = 7*pi feet
The equation for a circle is PiD. The diameter is double the radius, so it is 7 yards in this case. The circumference is 7*PI. Which is approximately 21.98.
The circumference of a circle (C) is the diameter (D) times pi (approximately 3.14 or 22/7). So, the equation would be: C=D*3.14. For example, if the diameter was 4', the circumference would be 12.56'.
The circumference of a circle with a 28 unit diameter is: 88cir=dx22/7
The diameter is 7
(Circumference) divided by (diameter) = (pi) (Circumference) = (diameter) times (pi) (Diameter) = (circumference) divided by (pi) (pi) = an irrational number, approximately = 3.14 or 22/7 .
7/pi = diameter
circumference of a circle = pie times the diameter = 22/7 x diameter = 22/7 x 7 inches = 22 inches
