.
The perimeter (circumference) of the of circle is pi x diameter:
.
The portion of the whole circle that is the arc of the sector is:
230 degrees/360 degrees=0.639
.
The length of the arc portion of the sector is:
.
The two sides of the sector are each a radius so 2(13cm)=26cm
.
The entire perimeter of the sector will be the length of the arc + the two sides:
P=perimeter of sector=
