shaded region rounded 200 not rounded 204.64 area
circle rounded 500 not rounded 452.39 area
pentagon rounded 248 not rounded 247.75 area
I looked up "How to find area of a pentagon" and this formula
[tex]A =\frac{1}{4} \sqrt{5(5+2\sqrt{5})}a^{2} =\frac{1}{4}*\sqrt{5(5+2*\sqrt{5})}*12^{2}=247.74875[/tex]
came up when I inputted the side length into it which is 12. This could be wrong but g00gle has a feature for this so I think it's correct.
Then, I found the area of the circle. I first had to find the radius of the pentagon which I think is 12. (It should be the same as the radius of a circle.) So, I found a calculator that found the area of the circle based on its radius and the answer was 452.39.
subtract the areas and u get the thing and then round it.
(btw I had to sensor g00gle because Brainly wouldn't let me post it.)
