Answer:
21.5%
Step-by-step explanation:
The area of the 4 circles together = 4×π×12^2
The area of the square = 48^2
then the probability that the point is in one of the circles =
(4×π×12^2)÷48^2
=0.785398163397
Therefore, the probability that the point is not in a circle =
1 - 0.785398163397 = 0.214601836603
converted into percentage : 21.4601836603
rounded = 21.5%

Answer:
15,17,19
Step-by-step explanation:
<em>Here's</em><em> your</em><em> solution</em>
<em> </em><em> </em>=> let the first number be x
=> then second and third number will be
(x + 2) and (x + 4)
=> now it's given that sum is 51
=> so, x + (x + 2) + (x + 4) = 51
=> 3x + 6 = 51
=> 3x = 51 - 6
=> 3x = 45
=> x = 45/3
=> x = 15
hence ,the following number are , 15,17,19
hope it helps
