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 diameter of a circle with a 12-foot circumference is about 3.82 feet. (circumference divided by Pi = diameter).
The circumference of a circle with a diameter of 12 is about: 37.7 (C = diameter x Pi).
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.
The equation for the circumference of a circle is Pi x D (Pi multiplied by the diameter). So, if you mean the circle has a diameter of 12 feet, then we must multiply 12 by Pi. (Pi is approximately 3.14) So the circumference is 12 x 3.14 = 37.68 feet, or a bit over 37' 8".
The diameter of a circle with a 12-foot circumference is about 3.82 feet. (circumference divided by Pi = diameter).
Circumference of a circle = 2*pi*radius or pi*diameter
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).
38/pi = 12.09577567 or about 12 feet
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.
