Answer:
Area of circle = 50.24 units
Option J is correct answer.
Step-by-step explanation:
We need to find the area of a circle with centre (2, 3) that passes through (2,7)
The formula used to find area of circle is:

We need to find radius.
The radius can be found using the distance between points (2,3) and (2,7)
The The distance formula is: 
Putting values and finding length
We have: 
Putting values and finding distance

So, we found Distance = 4
Therefore, the radius of circle is 4
Now, finding area:

So, Area of circle = 50.24 units
Option J is correct answer.
The approximate percentage of light remaining after passing through 6 feet of water, to the nearest tenth of a percent is 4.7%
<h3>How is the percentage of light remaining at a depth of 6 feet calculated?</h3>
The percentage of light remaining is calculated from the percentage of light remaining after a depth of one foot each.
Percentage of light remaining after 1 feet = 100 - 40% = 60%.
Percentage of light remaining after 6 feet = 60% × 60% × 60% × 60% × 60% × 60% = 4.7%
Therefore, the approximate percentage of light remaining after passing through 6 feet of water, to the nearest tenth of a percent is 4.7%.
