A square is inscribed in a circle of diameter 12 millimeters. What is the area of the shaded region? A square is inscribed in a circle with a diameter of 12 StartRoot 2 EndRoot millimeters. Everything outside of the square is shaded.

Recall that in a 45 – 45 – 90 triangle, if the legs each measure x units, then the hypotenuse measures x units.

(72π – 144) mm2
(72π – 72) mm2
(288π – 288) mm2
(288π – 144) mm2

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
