Answer:
D. [tex]\pi (8in)^{2}\times \frac{42}{360}[/tex]
Step-by-step explanation:
We are given that,
Radius of the circle = 8 inches
Central angle of the circle = 42°
As, we know,
Area of a sector of a circle = [tex]\pi r^{2}\times \frac{\theta}{360}[/tex]
So, substituting the values, we get,
Area of a sector the circle = [tex]\pi 8^{2}\times \frac{42}{360}[/tex]
Thus, option D i.e. [tex]\pi (8in)^{2}\times \frac{42}{360}[/tex] can be used to find the area of the sector.
