I'm not quite sure what your asking but if you just want to represent it then it is 57+b
4 x 23 = 92
four shoes cost $92 at Wallmart, but its the same at kohl's
wallmart price = kohl's price
$92 = $92
they are equal
Can you make it more understandable and put it all side by side how it was seen on your screen please so I can help?
The area of a circle is pi×r^2. and r = 36. but since the shaded area is only 1/4 of the area. so the answer is about 28.27 sq. cm.
