Question

Find the cost of fertilizing a playing field at $0.40 per square yard when the rectangular partof the field is 160 yd long and the diameter of each semicircle is 50 yd. Use pi=3.14

Answer 1

So I assume you mean a rectangular field with two semicircular ends...

c=.4(160*50+π25^2)

c=.4(8000+625π)

c=320+250π

c≈$1105.40 to nearest cent
