Assuming you mean the radius, which is half of the diameter:
4.56 m ÷ 2 = 2.28 m
The radius is the distance from the center to the outer edge of the circle. You can measure the diameter, the distance from side to side, and divide by 2.
Radias
The cord of a circle that contains the center of that circle is a diameter of that circle.
You do a diameter circle!!
To find the radius of a circle, you can measure the distance from the center of the circle to any point on its circumference. If you have the diameter, simply divide it by two, as the radius is half the diameter. In geometric problems, you can also use the formula ( r = \sqrt{A/\pi} ) if you know the area ( A ) of the circle. In coordinate geometry, if you have the equation of a circle in the form ( (x - h)^2 + (y - k)^2 = r^2 ), the radius is the square root of the constant on the right side of the equation.
The radius is the distance from the center to the outer edge of the circle. You can measure the diameter, the distance from side to side, and divide by 2.
If it's the perimeter of a circle you go C=pie x diameter or C= 2 x pie x radias = 2 pie radias. This is all confusing but the answer is 62.83
Pi times the diameter of a circle gives its circumference. Since the radius is 5 cm, the diameter is 10 cm, and pi x 10 cm is the answer, or 31.4159 cm.

12pi or about 37.699
circumference = 2*pi*radius
456m = 45 600cm
456m converts to 45,600cm @100cm per meter.
