To divide a circle into eight equal pieces with three straight lines, first draw two diameters that partition the circle into four sections. Next, separate and rearrange the sections, and then use a third line to cut them in half. The line segments inside the circle are chords, and diameters are chords that are in the middle of a circle.Continue Reading
Draw a light mark at the center of the circle you wish to partition. Use a ruler to draw a horizontal line across this mark. The line is a diameter that divides the circle into two parts.
Place a ruler so that it is perpendicular to the mark. Draw a line from the circle’s top to its bottom so that it splits into four equal parts.
Use a pair of scissors to cut along the diameters in order to separate the pieces. Place these pieces on top of each other so that they form a stack.
Lightly pencil a line down the middle of the stack’s top piece. Carefully use scissors to cut along this line. The circle should now be split into eight pieces that are the same size.
Measure the length of a curve by treating the curve as part of a complete circle. Once the diameter of the circle is known, it is possible to calculate the length of the curve.Full Answer >
The circumference of a circle is calculated by multiplying pi by the diameter, or 2 pi times the radius. The diameter or radius value is required to calculate circumference.Full Answer >
The length of an arc of a circle is equal to the angle subtended by the arc, in radians, times the radius of the circle. For an angle measured in degrees, the arc length is the angle, in degrees, times the radius times pi divided by 180.Full Answer >
The diameter of a circle can be calculated using the formula d = 2r, where "d" indicates the diameter and "r" denotes the radius of the circle. In terms of circumference, the diameter can be computed using the equation d = c/pi, where "c" represents the circumference and pi is approximately equivalent to 3.142. If the area of the circle is given, the formula d = sqrt (4a/pi) can also be used to solve for the diameter, where "a" denotes the area.Full Answer >
