The circumference is equal to r2*pie or 38.5 inches
Another answer:
Circumference of a circle = 2*pi*radius or pi*diameter
Circumference = 7*pi = 21.99114858 or 22.0 inches to one decimal place.
Diameter: 87.5/pi = 27.852 inches to 3 decimal places
Circumference of the circle: pi*1.675 = 5.262 inches to three decimal places
Circumference of circle: pi*2.13 = 6.692 inches rounded to 3 decimal places
circumference = 12*pi = 37.699 inches to 3 decimal places
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
Remember the circle equation C = pi d To find 'd' the diamter , algebraically rearrange . d = C/ pi d = 6 incnhes/ 3.141592.... d = 1.9098593147.... inches d ~=~ 1.9 inches
Divide the circumference of a circle by pi to obtain the diameter. Diameter of a 36 inch diameter circle is 36/3.1416 inches , or 11.459 inches.
Circumference of circle: 31*pi = 97.389 inches rounded to 3 decimal places
Circumference of circle: 17.4*pi = 54.664 inches rounded to 3 decimal places
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
Diameter: 87.5/pi = 27.852 inches to 3 decimal places
The circumference of a circle with a radius of 12.5 is 78.54 to two decimal places.
Circumference of the circle: pi*1.675 = 5.262 inches to three decimal places
If a circle has a circumference of 6 inches the diameter is: 1.91 inches (circumference divided by Pi = diameter).
If a circle has a diameter of 24 inches its circumference is: 75.4 inches (diameter x Pi = circumference).
If the circumference of a circle is 10 inches, the diameter is: about 3.183 inches. (circumference divided by Pi = diameter)
If a circle has a diameter of 12.8 inches its circumference is: 40.21 inches (circumference = diameter x Pi).
