7b. How many times does a tire with a diameter of 36 in. rotate when it travels a mile? **Tip: As there are 63,360 in. in each mile, 63,360 divided by circumference
= number of full rotations. Round up to the next whole number. *
O 561 rotations
O 281 rotations
O 880 rotations
O 440 rotations

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.
