Answer:
Probability of rolling a 2 and flipping a head will be
Step-by-step explanation:
If we roll one die then probability to get any one side is 
Therefore, probability to get 2 by rolling the die will be P(A) = 
Now we flip a coin then getting head or tale probability is 
Or probability to get head by flipping the coin P(B) = 
Probability of happening both the events (rolling a 2 and flipping a head) will be denoted by
P(A∩B) = P(A)×P(B)
= 
= 
Therefore, probability of rolling a 2 and flipping a head will be
A full circle has a circumference of 2πr and an angle of 2π radians.
Set up a proportion:
2πr - 2π rad
2r - x rad

The answer is D. 2 radians.
