Pt.3 pls someone help me again

Hi there!

We first want to find what fraction of the area this sector is. We can do this by observing the central angle, and also recalling that there are 360 degrees in a full circle. This means that this sector makes up 48/360 of the whole circle, or 2/15.

This means that we know is equal to 2/15 of the whole circle. We can then multiply that by 15/2, as .

Which would be our answer. Expanding with pi = 3.14 gives us an area of 113.04.

Hope this helps! Feel free to let me know if you have any additional questions about this problem.

i believe it's a.

i'm not sure on this one, most likely correct.
