Answer 1

Answer:

In any sector, there are

3

parts to be considered:

the arc length,

the sector area

the sector angle

They all represent the SAME fraction of the whole circle.

The arc length is a fraction of the circumference

The sector area is a fraction of the whole area

The sector angle is a fraction of
