Circumference= 37.68 feet. All you have to do is multiply the diameter by pi. Same with radius. Multiply the radius by two to get the diameter then do diameter times pi.
(pi= 3.14 or 22 over 7.)The circumference of a circle with a diameter of 12 is about: 37.7 (C = diameter x Pi).
Remember the circle eq'n C = pi d Algebraically rearrange d = C/pi Hence C = 12 pi = 3.141592.... ~ 3.1416 Substitute d = 12 / 3.1416 d = 3.8197,,,. ft. The answer!!!!!
The circumference of a circle with a diameter of 12 cm is: about 37.7 cm
The circumference of a circle is pi times the diameter, so it would be 12*pi or about 37.7.
If a circle has a diameter of 12 inches the circumference will be about 37.7 inches. (C = d x Pi)
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
The circumference of a circle with a diameter of 12 is about: 37.7 (C = diameter x Pi).
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
Remember the circle eq'n C = pi d Algebraically rearrange d = C/pi Hence C = 12 pi = 3.141592.... ~ 3.1416 Substitute d = 12 / 3.1416 d = 3.8197,,,. ft. The answer!!!!!
38/pi = 12.09577567 or about 12 feet
What does the '12ft 3 in ' represent???? The diameter or the radius???? Please clarify.
The circumference of a circle with a diameter of 12 cm is: about 37.7 cm
The circumference of a 12-foot-diameter circle is 37.7 feet.
For the small circle of diameter 6, the circumference is 18.84.
The diameter of a circle with a circumference of 12 is: about 3.82To to this calculation for other circles, just divide the circumference by Pi (about 3.1416). The result is the diameter.
The circumference of a circle is pi times the diameter, so it would be 12*pi or about 37.7.
The circumference of the small circle would be 18.84.
