`SA - 6.28r^2 = 6.28rh` Divide both sides by `6.28r`
`(SA-6.28r^2)/(6.28r) = (6.28rh)/(6.28r)`
`h = (SA-6.28r^2)/(6.28r)`

# 323 is 267 Percent of what?
## 323 is 267 Percent of 120.97
%
323 is 267% of 120.97
Calculation steps:
323 ÷ ( 267 ÷ 100 ) = 120.97
### Calculate 323 is 267 Percent of what?
• F
Formula
323 ÷ ( 267 ÷ 100 )
• 1
Percent to decimal
267 ÷ 100 = 2.67
• 2
323 ÷ 2.67 = 120.97 So 323 is 267% of 120.97

# Sum of Odd Positive Powers
## Theorem
Let $n \in \N$ be an odd positive integer.
Let $x, y \in \Z_{>0}$ be (strictly) positive integers.
Then $x + y$ is a divisor of $x^n + y^n$.
## Proof
Given that $n \in \N$ be odd, it can be expressed in the form:
$n = 2 m + 1$
where $m \in \N$.
The proof proceeds by stro... | HuggingFaceTB/finemath | |
