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.
