The circumference of a circle equals 2(pi)r where pi = 3.142 and r = radius. In this case we know diameter not radius, but remember that diameter = 2r, so 12 = 2r r = 6 Plugging this back into our first equation we get: 2(3.142)(6) Circumference = about 37.7 feet

If the circumferance of circle is 13 ft what is the diameter?
Diameter of circle: 13/pi = 4.138 ft to 3 decimal places
What is the diameter of a circle with a circumferance of 60 meters?
circumference = pi*diameter so diameter = circumference/pi = 19.1 metres.
To measure the circumferance of a circle with a known diameter?
If the diameter is known, don't bother measuring the circumference.Simply multiply the diameter by 'pi'.
What is the Circumferance of 8' diameter circle?
Just over 25' ( 8 x pi)
What is the circumferance of a circle if the diameter is 19?
19 pi, ie 19 x 3.1415 = 59.69
If the circumferance of circle is 13 ft what is the diameter?
Diameter of circle: 13/pi = 4.138 ft to 3 decimal places
What is the circumferance of a circle that has a diameter of 27?
What is 27 X 3.14? 27 pi
What is the diameter of a circle with a circumferance of 60 meters?
circumference = pi*diameter so diameter = circumference/pi = 19.1 metres.
To measure the circumferance of a circle with a known diameter?
If the diameter is known, don't bother measuring the circumference.Simply multiply the diameter by 'pi'.
What is the formula for finding the circumferance of a circle?
Either pi times the diameter or pi times twice the radius (which is the diameter)
What is the Circumferance of 8' diameter circle?
Just over 25' ( 8 x pi)
What is the diameter if a circle measures a circumferance of 39 inches?
39 inches / pi = 12.4 inches

19 pi, ie 19 x 3.1415 = 59.69
If the circumferance of a circle is 30 cm approximatley what is the diameter?
30/pi = just over 9.5 cm
What is the circumferance of a seven eighths inch circle?
7/8 inch circle has a diameter of 7/8 and a radius of 7/16=.4375 circumferance of a circle = 2*pi*radius = 2*3.14*.4375 =2.7475 or 7*pi/8
The radius of a circle with a circumference?
R(10) If you know the Circumferance, divide it by Pi (about 3.14). That will tell you the diameter. Half the diameter equals the radius.
Circumferance divided by diameter is called?
The circumference of a circle divided by its own diameter will leave you with pi which is about 3.142 correct to three decimal places.
