A cone always contain a right angle.
To solve for the volume of a cone, we need to get the radius of the cone and its height.
Volume of a cone = π r² h/3
radius is the line from the center of the circle of the cone going to the edge of the circle.
height is the measurement of the cone from its pointy tip going downward.
Assuming the radius of the cone is 3 in. and its height is 6 inches.
Volume of a cone = π * r² * h/3
V = 3.14 * (3in)² * 6in/3
V = 3.14 * 9in² * 2in
V = 56.52 in³

Answer:
x = 15
Step-by-step explanation:
create a proportion: <u> x + 10 </u> = <u> x + x + 10 </u>
5 8
cross-multiply: 8(x + 10) = 5(2x + 10)
8x + 80 = 10x + 50
80 = 2x + 50
30 = 2x
15 = x
Answer: 3x^3 -8*x^2 + 8*x + 3
Step-by-step explanation:
The standard form for a plolynomial is:
a*x^n + b*x^(n-1) + c*x^(n - 2) ........
We have:
(x-1)(3x^2-5x-3)
this is equal to:
3*x^3 - 5*x^2 + 3*x - 3*x^2 +5*x + 3
where the thing that i did is distribute the multiplication
this is equal to:
3x^3 -8*x^2 + 8*x + 3
ANSWER
|PQ|=10
EXPLANATION
The first line is
y=2x+8
We put y=0 to find the x-intercept.
0=2x+8
-2x=8
x=-4
(-4,0) are the coordinates of P.
The second equation is
y=2x-12
To find the x-intercept, we put x=0 into the formula:
0=2x-12
-2x=-12
x=6
The coordinates of Q are (0,6).
The distance between these two points.
|PQ|=|6--4|=10
