The area of the circle is radius squared times 3.14. That gives you an area in square feet.
The volume of the tank is that area times depth. That gives you a volume in cubic feet.
Your comment about fish per ft makes no sense at all. Did you mean 2 fish per five square feet? or 2 fish per 5 cubic feet?
Anyway, you have the formulas, I assume you can mulitply and divide it out.
The my Pond has a radius 8ft. I want to stock my pond withfish, 2 fish for every 5 FT. How many fidh do I need?hOW
you first find the radius and then multiply it by pi wich is about 3.14
To calculate the number of fish you need to stock your pond, let's first find the area of the pond using the formula:
Area = π * radius^2
Given that the radius of your pond is 8ft, we can substitute it into the formula:
Area = 3.14 * 8^2
= 3.14 * 64
≈ 201.06 square feet (rounding to two decimal places)
Now, if you want to stock your pond with 2 fish per 5 square feet, we need to calculate the number of fish using the following formula:
Number of fish = (Area / 5) * 2
Substituting the area into the formula:
Number of fish = (201.06 / 5) * 2
≈ (40.212) * 2
= 80.424
Rounding to a whole number, you would need approximately 80 fish to stock your pond.
To find the number of fish you need to stock in your pond, we'll first calculate the area of the pond's surface using the formula you mentioned: Area = radius^2 * 3.14.
Substituting the given radius of 8ft into the formula, we get:
Area = 8^2 * 3.14 = 64 * 3.14 = 200.96 square feet.
Now, let's determine the number of fish needed. According to your comment, you want to stock the pond with 2 fish for every 5 square feet. To calculate the required number of fish, we'll divide the pond's surface area by 5 and then multiply by 2.
Number of fish = (Area / 5) * 2.
Number of fish = (200.96 / 5) * 2 = 40.192 * 2 = 80.384.
Since you can't have a fraction of a fish, we round it down to the nearest whole number. Therefore, you would need approximately 80 fish to stock your pond.
