Find the area of the circle with a circumference of 30 pi write your solution in terms of pi a=196pi mm2
a=256pi mm2
a=225pi mm2
a=196 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.

The correct answer is c
