Step-by-step explanation:
Radius of circle = 8 cm.
Circumference of the circle = 2xpix8 = 50.28571429 cm.
Area of the circle = pix8x8 = 201.1428571 sq cm.
Perimeter of the sector = 25 cm.
The arc length of the sector = 25–8–8 = 9 cm.
If 50.28571429 cm encloses 201.1428571 sq cm, then 9 cm of the arc with the two radii will enclose 201.1428571*9/50.28571429 = 36 sq cm.
