The central angle and the length of arc are related by the formula:
Length of arc = (θ/360) * 2πr
Where θ = Central angle.
If the central angle is one quarter of the entire circle, the length of arc would also be one quarter of the entire circumference of the circle.
The answer is 9 just reciprocate the 1/3 and the multiply the 9 by 3

Answer:
The statement is true.
Step-by-step explanation:
Let us assume that x is the required number.
Now, given that the number minus 3 is at most 12.
Hence, x - 3 ≤ 12
⇒ x ≤ 15 ......... (1)
And also given that 1 more than 2 times the number is at least 25.
Hence, 2x + 1 ≥ 25
⇒ 2x ≥ 24
⇒ x ≥ 12 .......... (2)
Therefore, from equations (1) and (2) we get the number must be greater than or equal to 12 or less than or equal to 15.
So, the statement is true. (Answer)
49.5 is the answer because 66% equals 2/3.
