Question

Basically look at the picture I don’t even know what to say

Answer 1

C

Explanation:

x =
`(2)/(3)` πr³ ( multiply both sides by 3 to clear the fraction )

3x = 2πr³ ( divide both sides by 2π )

`(3x)/(2\pi )` = r³ ( take cube root of both sides )

`\sqrt[3]{(3x)/(2\pi ) }` = r

Answer 2

`r=\sqrt[3]{(3x)/(2\pi )}`

Explanation:

This question make look scary, but don't judge its book by its cover.

`x=(2)/(3) \pi r^(3) \\(2)/(3) \pi r^(3)=x\\r^(3) =x / (2\pi )/(3) \\r^(3) =x*(3)/(2\pi ) \\r^(3) =(3x)/(2\pi ) \\r=\sqrt[3]{(3x)/(2\pi )}`
