The answer is 5/16 because in total there are 16 possibilities when tossing a coin 4 times.
I think it is fifty-four hundred
10 because here's an example if three people are sharing a pie with 30 pieces everybody gets 10 because 30 pieces of pie divided by three people is 10 :) hope this helps!
The radius would be 8. The formula is 2πr. So 16 divided by 2 is 8. Therefore, the answer is 8.
