can someone help me solve this

you have to be 18 to use this site.

you should also tell your teacher, parent, or an adult at your school that you're having problems with math and want help. I'm assuming this is a summer school class, which would mean you flunked math during the regular school year. get some help, and I don't mean just with individual math problems. get a tutor or get in some kind of mentoring program, or something. please do this for your own good, OP.

unless of course you're just being lazy, in which case fuck off. and seriously, don't come back here til you're 18.

>approximated

That is the EXACT area, after all we use pi, not an approximation of it like 3

Sorry, I have a learning disability.

Also, I've been on the internet long enough to know how edgy 4chan could be.

4*3*7^2 = 12*49 = 588

You use exactly Pi, not an approximation, do you?

What number is that, exactly?

are you serious?

Bullshit. You're lazy and stupid.

If you're over 18, a fine homosexual gentleman or lady with a strapon would glady solve this problem for you in exchange for your holes.

That's an approximation dumbfuck.

Stop being irrational.

And if you're under even more gentlemen and ladies.
