Put a peg in the ground where you want the centre of the circle. Tie a string to the peg - loose enough so tat the string is free to rotate around the peg. Measure 5 metres along the string, from the peg, and at that point tie something that will mark the ground - a stick, for example.
Walk around the central peg, holding the stick to the ground and keeping the string taut.
A congruent figure is identical to another figure. Example would be like a circle with the radius of 12 meters, then the congruent figure would have to be a circle with a 12 meter radius.
You divide the area of the shaded region by the area of the full circle. For example, if the radius of the shaded region is 2 meters, the probability would be 4pi / 36pi, or 1/9. If the shaded region is a 'slice' of the circle, the chance is just the fraction of the circle which the 'slice' is.
It is not possible to have a circle with an area of 100 metres. Areas must be measured in square units, such as square metres. Assuming that the circle had an area of 100 sq metres, its radius would be 5.64 metres (to 2 dp).
Radius of circle: 8/2 = 4 inches
The radius would be 49.987 yards.
200m radius describes a circle which from it's outer edge to it's center is 200 meters. The circle itself, therefore, would be 400 meters across.
The circumference of a circle can be calculated using the formula C = πd or C = 2πr, where d is the diameter and r is the radius of the circle. For a circle with a radius of 3 meters, the circumference would be C = 2π×3 =6π meters, or approximately 18.85 meters when rounded to two decimal places.

It would be pi x 2 x 26.5 meters 3,1415 x 53 =166.49 meters (approximately)
Since diameter is twice its radius, the radius of this circle would be 60
The process you would use to find the circumference of a circle completely depends on what information you already have about the circle. For example, you might be given the circle's area, or its radius, or its diameter, or the length of one radian of arc along the circumference, and each of those would require a different method to find the circumference. The easiest example is the one where you know the circle's diameter. In that case, simply multiply the diameter by (pi) to get the circumference. The next easiest case is the one where you have the circle's radius ... let's say the radius is 1.5 meters. Knowing that the radius is half of the diameter, you first double the radius, and find that the diameter 3.0 meters. Then you get the circumference just as you did in the first example ... multiply the diameter by (pi). With a radius of 1.5 meter, you would find that the circumference is about 9.425 meters.

The radius would be 9 meters because the diameter is double the radius.
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
The radius of a circle is half the diameter. So if the diameter is 5cm, the radius would be 2.5cm.
