Sagot :

The area of a circular sector is given by:

[tex]A=\frac{\theta\pi r^2}{360}[/tex]

Where:

θ = 170°

r = diameter/2 = 15/2 = 7.5 ft

π = 3.14

Substitute the values:

[tex]A=\frac{(170)(3.14)(7.5)^2}{360}=\frac{(170)(3.14)(56.25)}{360}=\frac{30026.25}{360}=83.41[/tex]

Therefore Chris is not correct.

Answer: Area = 83.41 ft^2
