Answer:
A. Because 1/2 = 4/8 and 4/8 - 3/8 equals 1/8
I know you have to divide because to change a small number to a larger number divided so divide all of the angles
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%.
I think the answer is D because its multiplying by 2 each time
