V= pi Times r squared times h
First divide both sides by pi and h
V / pi h = r squared
Square root both sides.
The square root of v /pi times h = r

Sorry, don't even think i've learned this yet, maybe look up a video from khan academy?
Answer:
k = 13
Step-by-step explanation:
20 ^ k / 20^4 = 20^9
knowing the laws of exponents, diving two numbers of the same base with exponents is like subtracting the exponents, so
k^x / k^y
= k ^ (x - y)
apply that knowledge here
20 ^ k / 20 ^ 4 = 20 ^ 9
20 ^ ( k - 4 ) = 20 ^ 9
now the bases have no use here so ignore them, and just calculate the exponents
k - 4 = 9
solve using inverse operations
k - 4 = 9
+4 +4
k = 13
The digit 2 would be in the hundred thousands place because if you say it out loud its "three million, two hundred fifty four thousand, one hundred and seven"
