Question

Any answers plzzzzzz​

Answer 1

`a= 3r {}^(2)`

`\sqrt{ (a)/(3) } = r \\ (1)/(3a) = r {}^(2) \\ (1)/(3a) (1)/(3) = r {}^(2) (1)/(3) \\ a = 3r {}^(2)`

Answer 2

A = 3
`r^(2)`

Explanation:

r =
`\sqrt{(A)/(3) }`

r =
`((A)/(3))^(1/2)`

square both sides:

`r^(2)` =
`(A)/(3)`

multiply 3 to both sides:

3
`r^(2)` = A
