If the diameter of a circle is 9 the circumference is: 28.3
circumference = pi * diameter so, diameter = 9/ pi = 2.86
If 9 cm is the diameter, I think the circumference should be 9 times pi centimeters, which is approximately 28.274333882308139146163790449516 centimeters for the circumference. *********************************************** The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. Thus: 3.14 x 9 = 28.26cm
Since the circumference is the diameter times pi, it follows that the diameter is the circumference divided by pi. Pi is approximately 3.1416.
Circumference of a circle is: 2*pi*radius or pi*diameter
(9 pi) inches is.
If the diameter of a circle is 9 the circumference is: 28.3
If a circle has a circumference of 9, the diameter is: 2.864
(pie)(diameter)=(circumference) (pie)(9)(2)=18(pie)=56.549
A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
circumference = pi * diameter so, diameter = 9/ pi = 2.86
Circumference of any circle = (pi) x (diameter) Circumference of this circle = (pi) x (9 feet)
Circumference of 9 inches: 2.864788975654119in. (for pi I used 3.14159265358979) Diameter of 9 inches: 4.5in.
The circumference of a circle is equal to Pi x diameter. So, 9 x 3.1416 = about 28.274 units.
56.548667764616276 circumference = PI * diameter
To find the diameter of a circle with a 9-inch circumference, you can use the formula for circumference: C = πd, where C is the circumference and d is the diameter. In this case, C = 9 inches. Rearranging the formula to solve for the diameter, you get d = C / π. Substituting in the known values, the diameter of a circle with a 9-inch circumference is approximately 2.87 inches.
