So, the area of a circle is a=pi r^2
so do that and get a=pi(4)
and since the circle touches the edge of the rectangle, the rectangle is 4 cm tall, so 4*8 is 32 and pi(4) is about 12.56, so 32-12.56 is 19.44, and I believe that is the answer. (19.4)
Answer:
0.10x + 0.13y = 10780
x + y = 100000
x = 74000 --------------10%
y = 26000 --------------13% (more risky)
