It has been a while since I had done these, but I believe you need to multiply all the measurements together
The answer is <span>B. The cable company decrease the monthly charge by 20%</span>
20 because 16 is greater than 15 and we round the number up.
cylinder:
V = πr²h
V = 3.14(2)² * 3
V = 3.14(4) * 3
V = 3.14(12)
V = 37.7m³
rectangular prism:
V = lwh
V = (2.4)(9)(5)
V = 108m³
the entirety of the sculpture:
V = volume of cylinder + volume of rectangular prism
V = 37.7 + 108
<u>V = 145.7m³</u>
