Answer :
Do you have a picture of your question?
ok
angle = 145
radius = 18 ft
[tex]\begin{gathered} \text{Area = }\frac{\theta}{360}pi(r)^2 \\ \text{Area = }\frac{145}{360}(3.14)(18)^2 \\ \text{Area = (0.402)(3.14)(324)} \\ \text{Area = 409 ft}^2 \end{gathered}[/tex]Well the result from the calculator is 409.77 ft^2
I need to round to the near tenth or hundredth?
Rounding to the nearest tenth = 409.8 ft^2
Rounding to the nearest hundred = 409.77 ft^2
