Answer:

Step-by-step explanation:
To find the volume of the sphere we need to know its radius.
And the radius can be found with the information we have about the surface area.
The formula for the surface area is as follows:

from this formula we clear the radius r:

and we substitute the known value of the surface area, and also the value of
:

and now that we know the radius we find the volume:

the volume of the sphere is 
Answer: The answer here is 45* because all you need to do is 180-72-63 then BAM you get your answer :)
Answer: 9
Step-by-step explanation:
Add 20, 12, and 32 together then divide by 7 because it says "One week" and a week is 7 days. So, it should be like 20 +12 + 32= 64
64 / (divided by) 7 = 9
Remove the radical by raising each side to the index of the radical.
x > 29/4
