Steve has a steel barrel with a diameter of 4 feet that can be filled to a depth of 4.3 feet with oil. what is the volume of the barrel? use = 3.14 a. 54.008 cubic feet b. 51.6 cubic feet c. 78.128 cubic feet d. 17.708 cubic feet

Option A. 54.008 cubic feet

Step-by-step explanation:

we know that

The volume of the barrel is equal to

----> volume of the cylinder

we have

----> the radius is half the diameter

---> is the depth

substitute

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
