Martina is building a fence around her garden. For every 4 feet of fencing, the cost is $32. Complete the table below showing the length of the fence and the cost.
Length of fencing (feet)

For every foot of fencing, it costs $8. This should help us easily solve the question.

1st missing number: 48

2nd missing number: 56

3rd missing number: 9

4th missing number: 80

Length of fencing: 4, 6, 7, 9, 10

Cost : 32 , 42, 63, 72, 90

Step-by-step explanation:

im not sure if the cost is correct but someone else might have the cost right

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

the answer would be a 24

c=2πr=2·π·3=24
