V = 
is the formula to find the volume of a sphere.
First cube the radius (12)
= 1728
Now multiply 1728 by 4/3 by multiplying it by 4, and then dividing the result by 3.
1728 x 4 = 6912
= 2304
Now, we multiply this number by to get our final answer.
You typically use 3.14 to approximate.
2304 x 3.14 = 7234.56
Therefore, the volume of a sphere with a radius of 12 will be approximately 7234.56
Hope this helps!!
Let me know if there's anything you don't understand and I'll try to explain as best I can.

Answer:
(6, - )
Step-by-step explanation:
Given the 2 equations
3x - 4y = 20 → (1)
4x - 2y = 25 → (2)
Multiplying (2) by - 2 and adding to (1) eliminates the y- term
- 8x + 4y = - 50 → (3)
Add (1) and (3) term by term to eliminate y
- 5x = - 30 ( divide both sides by - 5 )
x = 6
Substitute x = 6 into either of the 2 equations and evaluate for y
Substituting into (1)
3(6) - 4y = 20
18 - 4y = 20 ( subtract 18 from both sides )
- 4y = 2 ( divide both sides by - 4 )
y = = -
Solution is (6, - )
