Which is true about a circle is inscribed in a hexagon?
The radius of a circle inscribed in a regular hexagon equals the length of one side of the hexagon.
The circle is centered at the origin and the length of its radius is 8 What is the circle's equation?
The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.
What is segments with the same length?
The answer depends on what they are segments of: the answer will be different depending on whether they are line segments or segments of a circle or even different circles.

The equation for a circle is x2 plus y2 equals 100 What is the length of the circle's radius?
10 Both the x-intercept (y=0) and the y-intercept (x=0) have a length of 10 units.
In circle P BC equals 24 what is the length of arc ABC?
The length of the arc of ABC is 22pi. You can get this answer by completing this equation 330/360*24pi, which will give you 22pi.

Can a circle be drawn with any center and any radius?
The center of a circle is the same for all circles but the length of the radius can change
What is the length of a chord of the circle x2 plus y2 equals 72 which is tangent to the circle x2 plus y2 equals 18?
The circles are concentric with centre (0,0). The radius of the outer circle is sqrt(72), that of the inner circle is sqrt(18). By Pythagoras, the length of the semichord is sqrt(72 - 18) = sqrt(54) units. Therefore the chord is 2*sqrt(54) = 6*sqrt(6) = 14.679 units (approx).
How do you find the diameter of a circle if you have the circumference?
C=2(3.14)rThis is circumference equation for circles. If you have the circumference, you need to input it into the equation and solve for r. r is the radius of the circle, so to determine the diameter, which is 2 times the length of the radius, you just need to multiply the number you got for r times 2.
Why are all the diameters of a circle the same length?
They are not all the same length. If that was the case all circles would be the same size.
