Is the radius one fourth of the circumference?
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
What is the formula of a circumference?
circumference=r2pi
What is a diameter of a 18 inch circumference?
The formula for circumference is pi*d = circumference. Therefore just divide the circumference by pi to get diameter. Approx. answer = 5.73
What formula is used to find the diameter when you know the circumference?
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
How do you find the area of a cirle with the circumference?
Area = circumference squared... You do circumference divided by 4,... and then divide that by Pi.
What is 15dm squared?
15dm squared is 225dm.
150 cm equals how many dm?
150cm=15dm
150 centimeter equal to decimeter?
150cm = 15dm There are 10cm in a decimeter.
What is the circumference of a loonie?
A circumference is 4
Is the radius one fourth of the circumference?
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
Why is circumference equal to 2 times Pi times r?
Circumference = pi times diameter or Circumference= two x pi x radius. Now remember the diameter of a circle is the straight line from one edge of the circle, through the centre to the opposite edge. The straight line from the edge to the centre is the radius, and then from the centre to the opposite edge is another radius. So the diameter is the length of two radii. Algebraically express as d = 2r. So Algebraically C = pi*d Substituting the 'd' for '2r' C = pi2r However in algebra coefficient numbers are expressed to the left. Hence C = 2pir Why 'C' is this expression I would have to go into some 'very heavy' differential calculus. Suffice it to say, the ancients found that the circumference traced by a donkey/mule driving water out of well was directly proportional to the diameter, twice the length of the tether(2 radii). From this they discovered that for however long the the tether and the circumference were. they had a constant of proportion C directly related to diameter. This is equated to C = kd And k = C/d , which was founf to be 3.141592..... which now call 'pi'. for any sized circle. So today in school you learn C = pi d or C = 2 pi r And for circular area(A) A = pi r^(2) The 'pi' youare given in school is proabably 3.14 , 3.1416 or 22/7 . However, these values are Approximatons, because 'pi' is an irrational number. Hope that helps!!!!!!
What is the circumference of a circle with the radius of 43?

Circumference in a sentence?
circumference of the tire.
What is the circumference of 7.8cm?
circumference = 24.5
If circle circumference is 12 what is the radius?
Circumference = 12Diameter = Circumference/piRadius = Diameter/2 = circumference/(2 pi) = 1.9099 (rounded)
What definition of circumference?
The circumference is the distance around a closed curve. Circumference is a special perimeter.
