Which is a true statement? a. –11.6 > 7.52 b. –5.39 > –4.21 c. 8.7 < 8.63 d. –6.29 < –4.81

Well first lets review the information on these numbers. A negative number is less than 0. So the bigger the negative number, the smaller it actually is.

So...

a) -11.6 > 7.52 (A negative is not greater than a positive!)
b) -5.39 > -4.21 (The bigger the negative the smaller the number -Nope!)
c) 8.7 < 8.63 (Nope- you can tell just by knowing the common number)
d) -6.29 < -4.81 (YES!!)

hope that helps!

central angle theta (in radians) = arc length / radius

So theta = 5.6/8 = 0.7 radians
