Answer 2

Answer:

To divide the disc of radius 5 cm into 7 equal parts, we need to divide the circle into 7 equal central angles.

The total central angle of the circle is 360 degrees. To find the central angle of each of the 7 parts, we divide 360 by 7:

360/7 = 51.43 degrees (approx)

So, each part will have a central angle of 51.43 degrees.

Using the formula for the arc length of a circle sector:

Arc length = (central angle / 360) x 2πr

where r is the radius of the circle.

We can find the arc length of each part:

Arc length = (51.43 / 360) x 2 x π x 5 = 4.33 cm (approx)

Therefore, each part of the disc will have an arc length of approximately 4.33 cm.
