1.Round r to nearest hundredth and theta to nearest hundredth of RADIAN

My work:

r^2 = x^ + y^2

r^2 = 4^2 + 6^2

r^2= 16 +36

r^ =52

r=7.21

I'm stuck on how to do theta in Radians, could you please assist

**Damon**, Friday, January 13, 2012 at 11:34amtan theta = 6/4 = 1.5

if your calculator does radians just do tan^-1 of 1.5

if it does degrees only then

tan^-1 1.5 = 56.3 degrees

56.3 * pi/190 = .98 radians
