The dolphin tank is similar to a cylinder. To find the volume of a cylinder, you use the formula:πr²h=V
For pi, we are using 3.14 and the height is 20 while the radius is 75.
3.14×75²×20
3.14×5,626×20
17,662.5×20=353,250
The volume is 353,250.0 ft³, which is the fourth answer.

The volume of the dolphin tank is 353250 cubic feet.

What is a cylinder?

"It is a three dimensional geometric structure with two parallel circular bases connected by lateral surface."

The volume of a cylinder is:

V = π × r² × h, where 'r' is the radius and 'h' is the height of the cylinder.

For given question,

the aquarium has a radius of 75 feet and a height of 20 feet.

r = 75 ft., h = 20 feet

Using the formula of the volume of the cylinder,

[tex]V=3.14 \times 75^2\times 20\\\\V=3.14\times5625\times20\\\\V=353250 ~~cubic~feet[/tex]

Therefore, the volume of the dolphin tank is 353250 cubic feet.
