Answer: A. 51%
Step-by-step explanation:
Area of circle =
, where r = radius of the circle.
In the figure below, we have the complete question.
According to that,
Radius of outer circle = 7ft
Radius of inner circle = 5ft
The probability that the thumbtack will be placed on the inner circle
[π is canceled from numerator and denominator
in percent, 
So, the probability that the thumbtack will be placed on the inner circle = 51%
Hence, the correct option is A. 51%.
Answer:
26.86
Step-by-step explanation:
P = 5 + 7 + 7 + C {divided by} 2
C = d {times} π
= 5 {times} 3.14
≈ 15.71
P = 19 + 15.71 {divided by} 2
= 19 + 7.855
= 26.855
≈26.86
