Answer:
a. 13; Equation = 2N - 7 = 19
b. 2; 8 - 3N = 2
Step-by-step explanation:
a. 2N - 7 = 19
- 2N - 7 + 7 = 19 + 7
<u>- 2N</u> = <u>26</u> = 13
2 2
b. 8 - 3N = 2
8 - 8 - 3N = 2 - 8
<u>- 3N</u> = <u>-6</u> = 2
-3 -3
Answer:
14,836.5 in^3
Step-by-step explanation:
The volume of a cylinder is given by the equation (πr^2)h where r stands for radius and h stands for height
The radius of the cylinder is 15 in
The height of the cylinder is 21 in
Volume=15×15×21×π
=14836.5 in^3
We have to find the exact value of
And it can also be written as
And
So we will get
