Yes. you need to know the diameter or radius of the circle and then the formula is:- Circumference = Pi*Diameter or Circumference = 2Pi*Radius. An approximate value for Pi is 3.14159.
If you mean of a circle, multiply the diameter by pi. Pi is approximately 3.1416. Add: C/D = pi = 3.1416 C = D x pi C = 18in x 3.1416 = 56.5488in = 57in rounded to two significant figures.
What is a "8 inch ball" ? Is 8 inches the diameter ? Then its diameter is 8 inches. Is 8 inches the radius ? Then its diameter is 16 inches. Is 8 inches the circumference ? Then its diameter is about 2.546 inches (rounded).
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
radius *2 = diameter so then plug the radius in... 4*2=8 8 is the diameter of the figure.
Diameter = 8 inches.Radius = 1/2 of the diameter = 8/2 = 4 inches.
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
Its diameter in mm = 8/pi
The circumference of a circle that has the diameter of 8 is: 25.1
Divide your circumference by pi = 3.141592654 and you get the diameter. The diameter is 8 / 3.141592654 = 2.546479089 inches.
The diameter cannot be "8 in and 5 in".
