2,-2
3,-3
10000,-10000
The 7 after the decimal is in the tenths place, so look at the one in the hundredths place. It is less than 5, so the 7 is not rounded up and stays 7. 877.7 is 877.71 rounded to the nearest tenth.
Answer:
8ft is the diameter so the radius would be half of that, so it's 4ft. Now substitute
![\pi4 {}^{2}](https://tex.z-dn.net/?f=%5Cpi4%20%7B%7D%5E%7B2%7D%20)
now solve 4^2=16 now multiply it by 3.14 (pi). 16×3.14= 50.24
1+3+6=10
40=10 units
diidde by 10
4=1unit
4 times 1=4
4 times 3=12
4 times 6=24
they paid $4, $12 and $24
