smaller powers (that's what 3.3^2 is, it means 3.3 to the second power) sometimes use different words to denote powers exg
x^2=x squared (square=2dimentionsl)
x^3=x cubed (cube=3 dimentionsl)
then x^4=x to the fourth, and so on
fifth, sixth, tecnth
It is B because tangent lines are always perpendicular to radii
Multiply .029 and 46. Add the product to 46.
