Answer:
-2n-1
Step-by-step explanation:
n +4n-7n-1
-2n-1
V = (1/3)·π·r²·h First, multiply both sides by 3:
3V = π·r²·h Now, divide by π·h
3V / (π·h) = r² Finally, take the square root of both sides:
±√[ 3V / (π·h) ] = r² If you are in algebra, you need the ±; if you are in geometry, you probably don't (usaully, you don't have negative radii).
I think it’s C. I don’t really know this but I thinks it’s 80.
