Question

A field is to be fertilized at a cost of $0.08 per square yard. The rectangular part of the field is 95 yards long and the diameter of each semicircle is 49 yards. Find the cost of fertilizing the field.

Answer 1

Find the area of the field

Answer 2

if the rectangular part is 95 yds long and the diameter of the semicircles is 49 yds, the area is:
95*49

Answer 3

ohh ok, i was like.. whatt??

Answer 4

that's just for rectangular area

Answer 5

i know

Answer 6

now add those two semicircles and find the whole area of a circle

Answer 7

A = pi*r^2 = pi * (49/2)^2

Answer 8

Total area:
95*49+pi*(49/2)^2
Total cost:
$0.08*(95*49+pi*(49/2)^2)

Answer 9

ok, thanks!!!
