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.
The radius of a circle is half of its diameter. If you are referring to a circle with a diameter of 90 meters, then the radius would be 45 meters. If 90 meters is already specified as the radius, then the radius is simply 90 meters.
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.
Oh, dude, you're hitting me with the math questions, huh? So, like, the area of a circle is πr^2, so for a circle with a radius of 1.5 meters, that would be π(1.5)^2. That's like 7.07 square meters. So, yeah, that's your answer.
The radius of 3.9 meters refers to the distance from the center of a circle or sphere to its edge. In geometric terms, if you have a circle with a radius of 3.9 m, the diameter would be twice that length, measuring 7.8 m. This radius can be used to calculate the area and circumference of the circle using the formulas: area = πr² and circumference = 2πr.
The radius of a circle is half of its diameter. If you are referring to a circle with a diameter of 90 meters, then the radius would be 45 meters. If 90 meters is already specified as the radius, then the radius is simply 90 meters.
A radius of 2 meters refers to the distance from the center of a circle or sphere to its outer edge. This means that if you were to draw a circle with a radius of 2 meters, every point on the circle would be exactly 2 meters away from its center. The diameter of such a circle would be 4 meters, as the diameter is twice the radius.
Well, isn't that just a happy little question! To find the radius of a circle, you simply divide the diameter by 2. Since the diameter of your circle is 6 meters, the radius would be half of that, which is 3 meters. Just imagine that radius as a little friend, bringing balance and harmony to your circle painting.
The circumference of a circle is calculated using the formula 2πr, where r is the radius. In this case, with a radius of 18 meters, the circumference would be 2 x π x 18 = 36π meters.
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.
Using 3.14 as Pi the area of circle is: 12.56
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.
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 would be pi x 2 x 26.5 meters 3,1415 x 53 =166.49 meters (approximately)
2 meters
Since diameter is twice its radius, the radius of this circle would be 60
