Plug in your calculator, (considering you have one) "2*3.14 (or pi symbol)*9
The equation for this is (2 times pi times radius)
Your answer should be 56.54866776
Rounding to the nearest tenth: 56.5
Nearest hundreth: 56.55
Hope this helped you :D
If a circle has a circumference of 9, the diameter is: 2.864
A circle or ellipse has a circumference. A number, such as 9, does not.
A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
If a circle has a circumference of 18pi, the radius is 9.
Circumference of any circle = (pi) x (diameter) Circumference of this circle = (pi) x (9 feet)
The circumference of a 9 circle is: 28.3
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
The circumference of 9 inch diameter circle is about 28.27 inches.
A circle with a radius of 9 inches has a circumference of 56.55 inches.
A circle or ellipse has a circumference. A number, such as 9, does not.
A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
If a circle has a circumference of 18pi, the radius is 9.
circumference = 2*pi*9
Circumference of any circle = (pi) x (diameter) Circumference of this circle = (pi) x (9 feet)
The circumference of a circle that is 9 cm wide is: 28.274 cm
Doubling the radius doubles the circumference.
