Answer:
235.62
Step-by-step explanation:
First you need to find the area of the big circle as a whole the equation is
A = pir^2
you need to plug in the radius of the big circle which would be
A = pi(10)^2
which equals
314.16
Then you need to find the area of the unshaded circle in the middle using the same formula but replacing the 10 with a 5
which equals
78.54
We then subtract the 78.54 from the 314.16 and we get 235.62 which is the area of the shaded circle to the right
