Question

Helpp!!! Plsss... I’ve to submit it tonight

Answer 1

R squared = (4pi)/A

Explanation:

I think what they're asking here is to make "r" in the place where "A" is. To do that, we need to divide both sides by r squared and that will give us A/r squared = 4pi.

Now we divide by A and get r squared = (4pi)/A

I hope this helps! :)
