What is the volume of the Cylinder ? Use 3 14 round the answer to the nearest hundredth . h = 7in r = 7in
Answers
Answer:
V = 1077.02 in³
Step-by-step explanation:
To find the volume of a cylinder, we use this formula:
V = πr²h
Let's plug in what we know.
V = (3.14)(7)²(7)
Evaluate the exponent first.
V = (3.14)(49)(7)
Multiply.
V = 1077.02 in³

Which statement about the system of equations y = 3x + 9 and y = 3x – 4 is true?
A. No solution
B. Infinite solutions
C. Exactly one solution
D. Different y-intercepts so there are two solutions
Answers
Answer:
A. no solution
Step-by-step explanation:
y = 3x + 9
y = 3x - 4
Let's solve this.
We can see that both equations equal y, so we can set them equal to each other.
3x + 9 = 3x - 4
Combine like terms.
[add 4 to both sides]
3x + 13 = 3x
[subtract 3x from both sides]
13 = 0
This statement is not true; therefore, there is no solution.
If we look at the graph below, we can see the lines are parallel. Parallel lines will never intersect and have no solution in a system of equations.
Hope this helps!

7x+31+21x-19= 180
7x+21x=180+19-31
28x=168
x= 168/28
x= 6
m∠p= (21x-19)°

Determine whether the Law of Cosines or the Law of Sines is needed to solve the triangle a = 11, b = 13, c = 7
Answers
Answer:
Step-by-step explanation:
Use the Law of Cosines:
c^2 = a^2 + b^2 - 2ab*cos C becomes
7^2 = 11^2 + 13^2 - 2(11)(13)cos C.
Once you have cos C, and then side c, you can use the Law of Sines to find the other two interior angles.
