Since the cost of seeding the field is proportional to the area of the field. Then we could calculate the cost of seeding the larger field by scaling up the cost of seeding the smaller field.
The area of the larger field is (4.5)(4.5) = 20.25 times the area of the smaller field, and so the cost of feeding should be 20.25 times.
Therefore, cost = 20.25(176) = $3564.

You have to get the ruler i guess sorry i’m not really good at this
Answer:
The value of f(3) = 28.26
Step-by-step explanation:
You have to do is to substitute r = 3 into the function :
![f(r) = 3.14 \times {r}^{2}](https://tex.z-dn.net/?f=f%28r%29%20%3D%203.14%20%5Ctimes%20%20%7Br%7D%5E%7B2%7D%20)
![f(3) = 3.14 \times {3}^{2}](https://tex.z-dn.net/?f=f%283%29%20%3D%203.14%20%5Ctimes%20%20%7B3%7D%5E%7B2%7D%20)
![f(3) = 3.14 \times 9](https://tex.z-dn.net/?f=f%283%29%20%3D%203.14%20%5Ctimes%209)
![f(3) = 28.26](https://tex.z-dn.net/?f=f%283%29%20%3D%2028.26)
I believe it’s D I hope this helped
Answer:
137
Step-by-step explanation:
180-43=137
the 180 comes from when you combine angles 1 and 2 (because they form a straight line). you subtract angle 1 and you will get angle 2. since angle 2 and 4 are across from each other, that means they are the same degree. so the answer would be 137
