Hint: First of all, construct a circle with the given radius of the circle. Then cut into 8 equal parts by dividing the central angle into 8 equal parts. By drawing all the diameter. we will get the circle into 8 equal parts.
Complete step-by-step answer:
Construct a circle of radius 4.5 cm as show in below figure:
We know that the diameter of the circle is equal to twice the length of radius of the circle.
So the diameter of the circle
Follow the below steps to divide the circle into equal parts:
Step 1: Draw a horizontal line of length 9 cm on the circle to divide into 2 equal parts as shown in figure 1.
Step 2: Draw a vertical line of length 9 cm on the circle to divide into 4 equal parts as shown in figure 2.
Step 3: Draw a line making an angle of with the horizontal line of length 9 cm on the circle as shown in figure 3.
Step 4: Draw a line making an angle of with the horizontal line of length 9 cm on the circle to divide into 8 equal parts as shown in figure 4.
Hence the circle of radius 4.5 cm is divided into 8 equal parts as shown in figure 4
Note: The diameter of the circle is equal to twice the length of radius of the circle. The area of each part is equal to part of the circle. If you notice here, we have also shown how to divide the circle into 2 equal parts and 4 equal parts of radius 4.5 cm.
