Answer:
A) The volume of the cylinder is <em>1017.9 in³</em>.
B) The volume of the enlarged cylinder is <em>27,482.7 in³</em>.
Step-by-step explanation:
<h3><u>What is the volume of the cylinder?</u></h3>
The radius of the cylinder is r = 6 in and the height is h = 9 in.
The volume of a cylinder can be found using the formula:
Substitute r = 6 and h = 9 into the formula.
- V = π(6)²(9)
- V = π(36)(9)
- V = π(324)
- V = 1017.876
The volume of the cylinder is <u>1017.876 in³</u>.
<h3><u>What is the volume of the enlarged cylinder?</u></h3>
If the cylinder is enlarged by a factor of 3, this means that each dimension is getting increased by 3.
Therefore, we need to multiply the original volume by a factor of three cubed; 3³.
- V_enlarged = V · 3³
- V_enlarged = 1017.876 · 27 = 27482.652 in³
The volume of the enlarged cylinder is <u>27,482.652 in³</u>.
Answer:
x=7,3
Step-by-step explanation:
x^2-8x+14=2x-7
Add 8x to both sides.
x^2+14=10x-7
Add 7 to both sides.
x^2+21=10x
x^2+7*3=10x
(x*7)+(x*3)=10x
x=7,3
Hope this helps plz hit the crown :D
