Answer 1

Делить надо на 4 части

Answer 2

Task: Dividing a Circle into Sectors

To divide a circle into sectors such that their angles make up 20% and 40% of the full angle, we can calculate the angles using the following steps.

1. Calculate the Full Angle: - The full angle in a circle is 360 degrees.

2. Calculate the Angles for the Sectors: - The first sector will have an angle of 20% of the full angle. - The second sector will have an angle of 40% of the full angle.

3. Divide the Circle: - Draw the sectors in the circle according to the calculated angles.

Calculation:

1. Full Angle: - The full angle of a circle is 360 degrees.

2. Angles for the Sectors: - 20% of 360 degrees = 0.20 * 360 = 72 degrees - 40% of 360 degrees = 0.40 * 360 = 144 degrees

Conclusion:

To divide the circle into sectors where the angles make up 20% and 40% of the full angle, the first sector will have an angle of 72 degrees, and the second sector will have an angle of 144 degrees.
