What are polar coordinates of (4,6)
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

tan 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
