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

Answer:

Total stocked of crayfish is   = 315.2

Step-by-step 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\times area\ of\ cylinder$

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

                                            $=20\times 2\pi \times3 (3+6) \times 0.3048$    [1 ft = 0.3048 m]

                                             = 315.2
