Answer:
24 cubic inches
Step-by-step explanation:
The formulas for the volume of a cylinder and cone are ...
volume of a cylinder = πr^2·h
volume of a cone = (1/3)πr^2·h
For the same radius and height, the cone has 1/3 the volume of the cylinder. Your cone's volume is ...
(1/3)·(72 cubic inches) = 24 cubic inches

Answer:
63
Step-by-step explanation:
The number of seats in a row will give an arithmetic sequence:
6, 9, 12, 15, ...
The first term is 6; the common difference is 3. The general term is ...
an = a1 +d(n -1) . . . . . . n-th term of sequence with first term a1, difference d
The 20th term of the sequence is ...
a20 = 6 +3(20 -1) = 6 +57 = 63
There would be 63 seats on the 20th row.
Answer:
(0,-3)
Step-by-step explanation:
2x-y = 3
x+2y = -6
Multiply the first equation by 2 so we can eliminate y
2(2x-y =3)
4x -2y = 6
Add this to the second equation
4x -2y = 6
x+2y = -6
-----------------
5x +0y = 0
x = 0
Now find t
x+2y = -6
0+2y = -6
2y =-6
Divide by 2
y = -3
