0Circumference of circle: 57*pi = 179 mm to the nearest whole number

Circumference of circle: 2*pi*3.5 = 22cm rounded to the nearest whole number

Circumference of circle: 14*pi = 44 units rounded to nearest whole number

10 is a number, not a circle or ellipse. It, therefore, has no circumference.

Circumference = 2*pi*2.3 cm

Circumference of circle in inches: 108*pi = 399 inches to the nearest whole number

Circumference of circle: 2*pi*35 = 220 cm rounded to the nearest whole number

Circumference of circle: 2*pi*35 = 220 m rounded to the nearest whole number

Circumference of the circle: 2*pi*7 = 44 cm rounded up to the nearest whole number

It depends on what the "32in" refers to: circumference, diameter, radius.

Circumference of circle: 2*pi*10 = 63 inches rounded up to the nearest whole number

Diameter of circle: 50/pi = 16 cm rounded to the nearest whole number

Diameter of circle: 792/pi = 252 inches to the nearest whole number

Circumference of circle: 7*pi = 22 feet rounded up to the nearest whole number

Its radius is: 1298/2*pi = 207 meters to nearest whole number

Diameter of circle: 25/pi = 8 inches rounded to the nearest whole number

Diameter of circle: 132/pi = 42 inches rounded to the nearest whole number

Since you didn't provide a number, I'll make one up. A circle with a circumference of 35 m has a diameter of approximately 11 m.

Radius of circle: 371/2*pi = 59 units to the nearest whole number

The circumference of a 4 foot diameter circle may be obtained by multiplying the diameter by pi, which is 3.1416 4 X 3.1416 = 13 (rounded to the nearest whole number)

Circumference of a CircleThe distance around a circle. It is equal to Pi () times the diameter of the circle. Pi or is a number that is approximately 3.14159. Example:What is the circumference of a circle having a diameter of 7.9 cm, to the nearest tenth of a cm? Using an approximation of 3.14159 for , and the fact that the circumference of a circle is times the diameter of the circle, the circumference of the circle is Pi × 7.9 3.14159 × 7.9 = 24.81…cm, which equals 24.8 cm when rounded to the nearest tenth of a cm.or you could just measure it using a string and save yourself the math

The circumference of a circle is equal to d(pi) where d is the diameter of the circle and pi is, well, pi.In case you do not know what pi is, it is an irrational number roughly equal to 3.14159265358979... that is all I remember. If you are still confused, check "circumference" on wikipedia, the free encyclopedia.

No because the circumference of a circle is pi times diameter and pi is an irrational number

The circumference of a circle divided by its diameter is equal to pi which is an irrational number.

Because the circumference of a circle divided by its diameter is equal to pi which is an irrational number.
