It would be greatly appreciated! i'll give a brainliest if you can explain how you got the answer too that would a lot!

Well to answer this problem we will have to find the area of the circle and the area of the square surrounding the circle.
To find the area of the circle, we can use the formula A=
We need the radius to find the area, and we already know the diameter. The radius is just half of the diameter. Half of 10 is just 5.
So just plug in the nunbers into the equation
A = ×
Simplify and we get that the area of the circle is about 78.54 inches.
Now we have to find the area of the square. Use the formula A = lw and plug in the numbers
A = 10×10
A = 100 inches
So just subtract 100 - 78.54 = 21.46
So our answer would be B. 21. 5 inches. Hope I helped!
