Either way. The probability of hitting the circle is:
P(C)=Area of circle divided by area of square
P(W)=(area of square minus area of circle divided by area of square
P(C)=(πr^2)/s^2
P(W)=(s^2-πr^2)/s^2
...
Okay with know dimensions, r=1 (because r=d/2 and d=2 so r=1), s=11 we have:
P(inside circle)=π/121 (≈0.0259 or 2.6%)
P(outside circel)=(121-π)/121 (≈0.9744 or 97.4%)
Well 120 is 1/3 of the square so the 9ft is 2/3 of the square so it is B
Answer:
42 because 3 tens is 30 and 12 ones is 12. so you do 30 + 12 = 42
I’m not a true percent sure but I think it’s C
