Answer:
H. 1/9.
Step-by-step explanation:
The area of a circle is calculated by solving for π.
The smallest circle has an area of π = π * 1 = π.
The middle ring will then have an area of π - π = π * 4 - π = 4π - π = 3π.
The largest ring will then have an area of π - π
= 9π - 4π = 5π.
5π + 3π + π = 9π
So, the probability of hitting the innermost circle will be π / 9π = 1 / 9.
Your answer is H. 1/9.

The distance between points (a) and (b) is the number of units between the points.
<u>Formula for halfway two</u>
Assume the lesser point is point (a)
To locate the halfway between points (a) and (b)
- Calculate the absolute difference between points (a) and (b) i.e. |a - b|
- Divide the difference into halves
- Add the value of one half to point (a).
The above steps is represented as:
Using the above formula, the halfway point between 5 and 11 would be 8
The formula can be used to calculate the distance between negative points, and absolute values are used to determine the number of units between the points
<u>Real world circumstance</u>
The formula can be used to calculate the halfway distance between two points on a track
<u>Fractional distance</u>
To determine the fractional distance, we simply replace the 1/2 in the original formula with the appropriate fraction.
Take for instance, three-fourths from (a) to (b) would be:
