Answer:
V=21.21
Step-by-step explanation:
Plug the measurements into the equation of a cylinder (V=πr^2h) to get the volume. Remember to divide the diameter by 2 to get the radius
3(4 - 2x) + 3x 12 + 3x 12 + 6x 12 - 3x 12 - 9x
12 - 6x + 3 • 12 + 3 • 12 + 6 • 12 - 3 • 12 - 9x
12 - 6x + 36 + 36 + 72 - 26 - 9x
-9x - 6x + 12 + 36 + 36 + 72 - 26
-15x + 156 - 26
-15x + 130
To find the amount of money she would earn for 3 hours. Simply take the value of 5.5 and multiply it by the value of 3, then convert 45 minutes to hours and multiply that amount to the amount she would be earning for 1 hour
Then add the values together, the final result would be $ 20.625.
