I sphere has a diameter of 24 units what is the volume in cubic units

1 answer:

6 0

The formula to find the volume of a sphere is:
4π(r³/3)=V
The radius is half of the diameter.
24÷2=12
4π(12³/3)=V
12.5663706(576)=V
7238.22947=V
So, the volume of the sphere is 7,238.22947 units³.

How do I add fractions

vivado [14]

Step-by-step explanation:

1 Find common denominator (lower numbers)

2 add numerators(top numbers)

3 put the numerator over the denominator

ex 3/4+2/8

3x2=6,4x2=8

3/4=6/8

6/8+2/8=8/8 or 1

Answer:

32.99

Step-by-step explanation:(you might have to round) if you have to round it or.. but this is it because

236.40 divided by 24 is 9.85 so

325 divided by 9.85 is 32.99 (you only need 2 decimal places for these kinds of questions because of repeating decimals).

Hope this helps :)

Solve each system by graphing.

Answer:

(x, y) = (4, -4)

Step-by-step explanation:

A graphing calculator makes graphing very easy. The attachment shows the solution to be (x, y) = (4, -4).

The equations are in slope-intercept form, so it is convenient to start from the y-intercept and use the slope (rise/run) to find additional points on the line.

The first line can be drawn by staring at (0, -2) and moving down 1 grid unit for each 2 to the right.

The second line can be drawn by starting at (0, 2) and moving down 3 grid units for each 2 to the right.

The point of intersection of the lines, (4, -4), is the solution to the system of equations.

Find the equation of a line that passes through left parenthesis 1 comma 6 right parenthesis(1,6) and is parallel to the graph o

max2010maxim [7]

Answer:

The equation for the new line in slope-intercept form is:

$y=4x+2$

Step-by-step explanation:

Since they give us an equation in slope-intercept form "y=4x+5", it is easy to extract the slope the new parallel line to this should have : "4" (same slope as the reference line)

We are also given a point the new line should go through : "(1, 6)"

So we can use the "point-slope" form of a line to find the equation of this new line:

$y-y_0=m(x=x_0)\\y=m(x-x_0)+y_0$

which for our case is:

$y=m(x-x_0)+y_0\\y=4\,(x-1)+6\\y=4x-4+6\\y=4x+2$
