Answer:
10.49823 centimeters
Step-by-step explanation:
Simply reverse the formula for the volume of a sphere: pi*r^3*(4/3).
So: pi*r^3*(4/3)=4846.59
r^3*(4/3)=1542.71751128
r^3*4=4628.15253384
r^3=1157.03813346
r=10.49823
Answer:
(5,4)
Step-by-step explanation:
-x+2y=3
3x-2y=7
Add the like terms( 2y and -2y)(-x and 3x)(3 and 7) together. Do this vertically. 2y and -2y cancel eachother out.
Divide both sides by 2
To find y, substitute x in for y in one of the equations
add 5 to both sides
Divide both sides by 2
