Surface area I think is the circle. So the formula to find the area of the circle is to do Pi times radius squared. Pi= 3.14 Radius in this case will be 2.2. (Radius is how much it measures out from the middle.) then you want to do 2.2 x 2.2 (since it's square) So the answer would be equal to (I think) 15.1976

Step-by-step explanation:
The number of times the coin landing head 8 out of 10 is simply:
C(10, 8)/2^10. At least 8 means, 8 or more. Since the events here are dependent on themselves the answer would be:
[ C(10, 8) + C(10, 9) + C(10, 10) ] / 2^10 = 56/1024 = 0.0546875
