The area = (N / 360) * (π * r^2)

N = degree

r = radius

Area = (150 / 360) * (π * (7)^2)

Simplify

Area = 64.14 cm^2

Now we have to subtract the value of the triangle.

The triangle has an area of 12.25cm^2

Subtract 12.25 cm^2 from 64.14cm^2

The area of the white region = 51.9cm^2

Step-by-step explanation:

Angle of a sector =

[tex] \frac{angle}{360} \times area \: of \: the \: circle[/tex]

=

[tex] \frac{150}{360} \times \frac{22}{7} \times{7}^{2} \\ \frac{110}{84} \times {7}^{2} \\ \frac{55}{42} \times {7}^{2} \\ \frac{55}{42} \times 49 \\ \frac{55 \times 49}{42} \\ \frac{2695}{42} \\ \frac{385}{6} = 64.167cm^{2} [/tex]

Off to school bye
