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
Answer:

21/29
Answer:
- A. 3x° + (8x - 20)° = 90°
Step-by-step explanation:
The two given angles are complementary and sum to 90°
Therefore correct choice is A.
Answer:
The answer to your question is (1, -2)
Step-by-step explanation:
See the graph below, in the graph, the solution is circled (1, -2). The solution is the point where the lines cross.
To check the answer, let's solve the system using algebra.
y = 2x - 4
y = 1 - 3x
2x - 4 = 1 - 3x
2x + 3x = 1 + 4
5x = 5
x = 5/5
x = 1
Find y by substitution
y = 2(1) - 4
y = 2 - 4
y = -2
Solution
(1, -2)
