Question

3. A cylindrical tank has a radius of 15 feet and a height of 45 feet. How many cubic feet of water can the tank hold?

A. 127,170 cu. ft.
B. 31.792.5 cu. ft.
C. 675 cu. ft.
D. 15,896.25 cu. ft.

Answer 1

Answer: 31.792.5 cu. ft. (choice B)

=================================================

Work Shown:

`V = \pi*r^2*h\\\\V \approx 3.14*15^2*45\\\\V \approx 31,792.5 \text{ cubic feet}\\\\`

The result is approximate since
`\pi \approx 3.14` is approximate.

Answer 2

`\huge\underline{\red{A}\green{n}\blue{s}\purple{w}\pink{e}\orange{r} →}`

B. 31.792.5 cu. ft.

Explanation:

Given,

Radius (r) = 15 feet

Height (h) = 45 feet

Volume = ?

therefore,

Volume of a cylinder = π × r² × h

Taking π ≈ 3.14..

V = 3.14 × 15² × 45

V = 31,792.5 cu. feet

So, the cylindrical tank can hold upto 31,792.5 cu. feet of water..
