Consider that the area of a sector of a circle is given by:


A=(\theta)/(360)\pi r^2

where θ is the angle of the sector and r is the radius.

For θ=40 and r = 8cm, you obtain:


A=(40)/(360)\pi(8cm)^2=22.34cm^2

The area of the small sector is about 22.34 cm^2.

Now, for θ=320 and r = 8cm, you obtain:


A^(\prime)=(320)/(360)\pi(8cm)^2=178.72cm^2

The area of the small sector is about 178.72 cm^2.
