Answer:
21.46 mm^2
Step-by-step explanation:
The area of the square is ...
A = s^2 = (10 mm)^2 = 100 mm^2
The area of the circle is ...
A = πr^2 = π(5 mm)^2 = 25π mm^2 ≈ 78.54 mm^2
Then the shaded area is ...
100 mm^2 -78.54 mm^2 = 21.46 mm^2 . . . shaded area
Step 1
we know that
The perimeter of a square is equal to
P=4*b
where
b is the length side of a square
<u>Find the perimeter of the square picture</u>
b=4 in
P=4*4=16 in
Step 2
<u>Find the maximum radius of the circular frame</u>
we know that
the perimeter of a square frame is equal to the circumference of the circular frame
the circumference is equal to



r=2.5 in
therefore
<u>the answer is</u>
the maximum radius of the circular frame is 2.5 in
