Answer:
h=1ft
Step-by-step explanation:
The volume of a cone is:
v=πr^h/3
plug in the values (I am assuming not 1/18π but 1/18×π):
1/18π= π1/3^2h/3
Get rid of the radius:
1/3^2=1/9
Continue:
π/18= πh/3*1/9= πh/18
Remove the denominators:
π=πh
Divide both sides by π :
h=1

Step-by-step explanation:
To evaluate x^6-x/4y when x=-4 and y =4
We get
-4^6-(-4)/4(4)
=4096+4/16
=4100/16
=256.25
Answer:
A.
Step-by-step explanation:
It's an isosceles triangle 45° - 45° - 90°, therefore y = 5.
In that triangle, sides are in proportion 1 : 1 : √2.
Therefore we have x = 5√2.
<h3>Answer: B. x = 5√2, y = 5</h3>
Other method.
You can use the Pythagorean theorem:
x² = 5² + 5²
x² = 25 + 25
x² = 2 · 25
x = √(25 · 2)
x = √25 · √2
x = 5√2
<h3>Answer: B. x = 5√2, y = 5</h3>
Answer: 65 = x + 2
x = 63 inches
