Yes
Answer:
I'm assuming there's a d option maybe? because this should be the answer
Step-by-step explanation:
Well you have the equation:
r-s
So all you need to do is plug in 1+2i as r, and 3+3i as s, and then you add like terms (kind of like how you can do 2 * sqrt(2) - 3 * sqrt(2) and you simply subtract the "coefficients")
Distribute the negative sign:
Combine like terms
Simplify:
divide both sides by pi
r=3
Radius is 3
diameter is double the radius, so diameter = 6
