8.61 would be 8.7 because you would use the 8 to round and if the number is larger then 5 then you raise the score if its lower then you lower the score
"5 or more raise the score 4 or less let it rest"
a good way to remember that
V=(4/3)(pi)r^3
r=7.5
V=(4/3)(pi)(7.5^3)
V=(4/3)(pi)(7.5^3)
V=(4/3)(pi)(421.875)
V=562.5pi ft^2
if you watnt to you can aprox pi=3.14
V=562.5*3.14
V=1766.25 ft^3
If Carla worked 6 hours and earned $13 an hour. All you need to do is multiply
13 x 6 = 78
So, Carla would have earned $78.00 for working the 6 hours.
Hope this helps you. :-)
