This question is a thought experiment.
It's essentially asking "Is 2πr² the same or not the same as π(2r)²?"
To figure it out, simply simplify π(2r)²
=π(2r)²
=π(2r)(2r)
=4πr²
Quite obviously, 2πr² is not the same as 4πr²
150 + 15x = 400
(-150) 150 + 15x = 400 (-150)
15x = 250
(/15) 15x = 250 (/15)
x = 16.67
