Which equation can be used to find the surface area of the cylinder? r = 6 cm
h = 8 cm
S-2 (8)2 + 2(12)(8)
S-2(6)? + 2(6)(8)
S = 2x{12)2 + 2x(12)(8)
S-2416)* +2F018)

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?
