Answer:
A. 2.9π(9²)
Step-by-step explanation:
You are expected to know that the area of a circle is given by the formula ...
A = πr²
and that r in the formula represents the radius of the circle, half the diameter.
The area of the circular base of the cylinder is the area of a circle with a radius of 9 feet. It will be ...
A = π(9²)
When that is multiplied by the height of the cylinder to find its volume, you have ...
V = Bh
V = (π(9²))(2.9)
This can be rearranged to match the form in answer choice A:
2.9π(9)²
If x is the number, then 1x-1
your answer would be y=-3x+14
Because -3/5 is a negative number
