To find the volume of this sphere you use the equations 4/3 times pi times r^3
For this question it would look like this 4/3 * 3.14 * 8^3=v
The answer is v = 2144.66058
To solve for the value of x, you can simply add all of the values and expressions together and make it equal to 180 degrees, since the sum of all angles in a triangle add up to this amount.
Then we can solve for X, by algebra.
Answer:
h = 3 cm
Step-by-step explanation:
Given that,
Diameter, d = 6 cm
Radius, r = 3 cm
Volume of the cone, V = 28.26 cm³
The formula for the volume of a cone is given by :
So, the height of the cone is equal to 3 cm.
The graph has no scale, so we can only make conclusions based on:
1. slope is negative (true), zero, or positive
slope is coefficient of x when equation is in standard form
2. y-intercept is negative, zero, or positive (true)
y-intercept is value of y when x=0
3. x-intercept is negative, zero, or positive (true).
x-intercept is value of x when y=0
Now let's look at the given answer choices:
A. 2x-y=7 => y=2x-7 => slope=2 >0 (false); => FALSE
B. 3x+2y=6 => y=-1.5x+6 => slope<0 (true); y-intercept>0 (true); x-intercept=6/3=2 >0 (true) => TRUE
C. y=5 => slope=0 (false) => FALSE
D. y=-4x+2 => slope=-4 <0 (true); y-intercept=2>0 (true); x-intercept=+1/2>0 (true) => TRUE
