Question 1160307
<font face="Times New Roman" size="+2">


Use *[tex \Large A\ =\ \pi{r^2}] to find the area of the circle of radius 15 feet and then divide by 5.


By the way, it would be absolutely dead wrong to express the answer to this question with greater accuracy than the nearest whole square foot because the radius measurement is given to the nearest whole foot.  Since ALL measurements are approximations, saying the radius is 15 feet only guarantees that the actual radius is in the range *[tex \Large 14.5'\ \leq\ r\ <\ 15.5']. This means that the area of a one-fifth sector of the circle would be in the range *[tex \Large 132.1\,\text{ft^2}\ \leq\ A_{sector}\ <\ 151.0\,\text{ft^2}], therefore adding decimal places to your answer would be utterly ludicrous.
