Answer:the answer is c
Step-by-step explanation:
Circumcerence = distance travelled in one full rotation = 2 x π x 8 = 16π
for 2 minutes and 15 seconds,
multiply 16π by 2.25 as 2 minutes is twice the distance of one rotation and 15 seconds is a quarter more
therefore answer is 36π = 113.1 inches
Answer:
={6,7,8,9,10}.
Step-by-step explanation:
We have an empty set: M={} and the set N={6,7,8,9,10}.
The union of these two sets are elements in M or N or both.
Since the M is a null set, 
Therefore:
={6,7,8,9,10}.
The union for the given sets is {6,7,8,9,10}.
Its either A or C they both have the same spot when it is graphed.
