A circle has center C, as shown below, and diameter 32 cm. Find the length of arc AB if mAngle ACB = 90 degrees. length of arc AB = m arc AB/360 degrees x 2 r

1. What fractional part of the circle's circumference is arc AB? (Hint: A circle has 360 degrees.)

2. Use the fraction you determined in Part I and the circumference formula to find the length of arc AB. Show your work and round your answer to the nearest hundredth. (2 points)

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
