Question

How to find the area of the shared portion. I have no idea how so can you explain it so that I can do others?

Answer 1

I hope this helps you



circle area=pi.5^2=25pi=78,5


polygons area=5×5×7,3/2=182,5


Shaded area=182,5-78,5=104

Answer 2

Get area of pentagon first
A=1/2ap
.5 (5)(7.3×5)
91.25
Area of circle= pi r^2
3.14x 5^2
78.5
91.25-78.5
12.75 in^2 is the shaded part
