Question

Determine how many crayfish may be stocked at 20 crayfish/sq meter in a 1000 gallon circular tank of 3 ft deep and 6 ft in diameter.

Answer 1

Total stocked of crayfish is = 315.2

Explanation:

Given data:

stocked of crayfish
`= 20 crayfish/m^2` in 1000 gallon water tank

size of tank = 3 ft deep and 6 feet diameter

let radius of tank is r and height of tank is h m

Total stocked of crayfish is
`=20* area\ of\ cylinder`

`= 20[ 2\pi r(r+h) ft^2]`

`=20* 2\pi *3 (3+6) * 0.3048` [1 ft = 0.3048 m]

= 315.2
