Best ResponseYou've already chosen the best response.0First one is \[\pi r ^{2}\] Second one is \[sr \theta\] Change your theta to radians for the second one.

Best ResponseYou've already chosen the best response.0so the first on would be 70.84 in^2?

Best ResponseYou've already chosen the best response.0The equation for the first one should look like \[\pi(4.75)^{2}\]

Best ResponseYou've already chosen the best response.0on the second one im still not sure what you ment

Best ResponseYou've already chosen the best response.0Ah sorry I wrote that wrong it is \[S = r \theta\] This means the area of the shaded region is equal to the radius multiplied by the angle. Change the angle to radians by multiplying it by \[\pi/180\]

Best ResponseYou've already chosen the best response.0Ah no wonder. Lol. I'm trying to make you use trig methods. Here, Multiply the 80 or whatever that is on the outside of that shaded region by \[\pi/180\] Then you simply that to get \[8\pi/18\] Which can be simplified further to \[4\pi/9\] Now you multiply, I beliebe it says 8.9?, by that using 3.14 for pi. Itd look like this \[8.9(4\pi/9)\]
