12
12pi or about 37.699
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
Since circumference equals pi times the diameter, if the diameter of a circle is 6, then its circumference is going to be pi times 6 or 6 pi.
the diameter would be 6.
What you do is, diameter divided by two, then multiply the diamter already divided in half multiplying by itself, then you would times the squared radius by pie(3.14) Example; diameter is 6 divided in half equals 2 because 6 divided by 3 equals two then spuare it which will be 4, then times it by pie or 3.14 :):):):):):):):):):):):):):):):)
As the diameter of a circle is twice the radius, a circle with a 6-foot radius would have a diameter of 6 x 2 or 12 feet.
Since with circles the radius is half the diameter, the diameter would be 6 cm.
The diameter is twice the radius - so, using your example, the diameter would be 6.
You have to find the diameter, 12, then you have to multiply that by 3.14 or pi... which equals 37.68.
If the diameter of a circle is 12 feet then its radius is 12/2 equals 6 feet
Well the radius is half the diameter so it would be 3 + 3 which is 6...therefore D = 6
The radius of a diameter is half the diameter, so the diameter is divided by 2, so 6 divided by 2 would be 3. The radius is therefore 3. :D
