You have a perfect square, 25 square inches in area, and you need to calculate the sides of a square exactly 1/2 the area. First person to give me the answer gets a free Titanium Upgrade.

You do not have to decimalize the answer, it can be in radical form.

25 sq in / 2 = 12.5 sq in

sqrt 12.5 = 3.5355339 in

to check:

(3.5355339)^2 = 12.5

Incorrect. The answer is always pi.

It's clearly either 2 or 288 ;)

Thank you... *sniff*

I think it was 10 millionth. I finally removed it from my sig a few weeks ago.

You win the consolation prize, a Carbon upgrade. You have been promoted to human (carbon unit). Congrats! :thumb:

you ought to do something more tricky.

like simplify: sin(x + pi/2) + cot ( pi/2 - x)

or figure out the length and width of a square box when the height of the box is length +5cm and volume is equal to 225cm^3.
