A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
Circumference of any circle = (pi) x (diameter) Circumference of this circle = (pi) x (9 feet)
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
28.26
If the diameter of a circle is 9 the circumference is: 28.3
A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
The circumference of 9 inch diameter circle is about 28.27 inches.
Circumference of any circle = (pi) x (diameter) Circumference of this circle = (pi) x (9 feet)
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
28.26
The diameter of a circle who's circumference is 28.26 miles is: nine (9) miles
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
28.27 units.
Doubling the radius doubles the circumference.
Circumference of a circle is equal to pi*diameter, so if d=9miles, c=28.3miles (to 1dp).
