Question

the rectangular part of the field below is 100 yards long and the diameter of each semicircle is 46 yards.Find the cost of reseeding the field at $0.60 per square yard how do you solve this so confuse

Answer 1

1. Diameters of the 2 semicircles would form the edges of rectangular field. So use the diameter as the width to calculate rectangular area.
2. Then calculate the area of the 2 semi circles, radius 46/2.
3. Add both rectangular and semi circular areas
4. Multiply total area with $0.60 to find total cost.

Answer 2

ok hold on

Answer 3

what about the 100

Answer 4

Yes 100 is the length of the rectangle. So, area of rectangular area = 100*46

Answer 5

o ok

Answer 6

so it is 40.100=? then u divide it by 2 then add it with the 0.60

Answer 7

Total Area = Rectangular Area + 2x Semicircle Area
= \[46\times100+2\times (\pi(46/2)^{2})/2\]

Answer 8

Does that make sense?

Answer 9

yes kinda

Answer 10

so the answer will be 6261.90 ?

Answer 11

Yes, thats your total area. Now you can find the total cost from the per sq. yard cost.

Answer 12

now u add that with the 0.60

Answer 13

Add? You sure about that?

Answer 14

idk

Answer 15

1 baseball bat costs $10. How much would it cost to by 10 baseball bats?

Answer 16

See where I am going with this? You are almost there...just think how you will get total cost.

Answer 17

mutiply

Answer 18

there you go!

Answer 19

ok so the answe is 3757.14
