Do you have a picture of your question?

ok

angle = 145

radius = 18 ft


\begin{gathered} \text{Area = }(\theta)/(360)pi(r)^2 \\ \text{Area = }(145)/(360)(3.14)(18)^2 \\ \text{Area = (0.402)(3.14)(324)} \\ \text{Area = 409 ft}^2 \end{gathered}

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
