The circle can be cut into pieces, separated, and fit together to form a parallelogram that has the same area. The height of the parallelogram is the radius and the base is half the circumference, which is r. The area is r(r), which is equal to r2.
Answer:
23+5y=23x +5
5y=23x-18
y=23/5x - 18/5
<u>y--7=</u>23/5
x-6
5y+35=23x-138
5y=23x-203
y=23/5x -203/5
