Ihave been stuck on this question for a while. i need to find the area of the shaded region and round to the nearest tenth.

818.4 in²

The area of a circular sector is given by ...

... A = (1/2)r²·θ . . . . . θ in radians

The area of the isosceles triangle with apex angle 150° is given by ...

... A = (1/2)r²·sin(θ)

Then the area of the shaded segment is ...

... A = (1/2)r²·(θ - sin(θ))

... A = (1/2)·(27.8 in)²(5π/6 -sin(5π/6)) ≈ 818.4 in²

If you (erroneously) use 3.14 for π, you get 817.9 in². Some answer keys expect you to use that value, even though it does not have sufficient accuracy for this problem.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
