Question

The main tank at an aquarium is a cylinder with a diameter of 203 ft and a height of 4 ft. What is its approximate volume? Use 3.14 for π. a. 129,400 ft3 b. 79,830 ft3 c. 236,560 ft3 d. 32,366 ft3

Answer 1

V=pi *r^2* h
diameter d= 2r=203
r=203/2=101.50
h=4
V=3.14 * 4 * (101.50)^2
V=129,400 ft^3

Answer 2

Answer:
`a.\ 129,400\ ft^3`

Explanation:

The volume of a cylinder is given by:-

`\text{Volume}=\pi r^2h`

Given: The diameter of cylinder = 203 ft.

Then the radius of the cylinder =
`(203)/(2)` ft.

The height of the cylinder = 4 ft.

Now, The volume of cylinder :will be -

`\text{Volume}=(3.14)((203)/(2))^2(4)=\\\\\Rightarrow\text{Volume}=129,396.26\approx129,400\ ft^3`
