A cylindrical swimming pool has a diameter of 16 feet and a height of 4 feet. About how many gallons of water can the pool conta

xenn [34]

Answer: 6029 gal

Step-by-step explanation:

The volume of cylinder is given by :-

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

Given : Diameter of cylindrical pool = 16 feet

Radius of cylindrical pool = $\frac{16}{2}=8\ ft$

Height of cylindrical pool = 4 feet

Now, The volume of cylindrical pool is given by :-

$\text{Volume}=\pi (8)^2(4)\\\\\Rightarrow\ \text{Volume}=3.14(64)(4)\\\Rightarrow\ \text{Volume}=803.84\ ft^3$

It is given that $1\ ft^3=7.5\ gal$

Therefore, The amount of water can the pool contain = $7.5\times803.84\ gal=6028.8\ gal\approx6029\ gal$

The radius of a cylindrical construction pipe is 1.5ft . If the pipe is 14ft long, what is its volume? Use the value 3.14 for π

Lady bird [3.3K]

Answer:

Volume of cylinder =989 ft cube

Step-by-step explanation:

<u>Volume of cylinder</u>

Volume V = πr²h

r - radius and h - height

It is given that,

The radius of a cylindrical construction pipe is 1.5ft and

Length of pipe = 14 ft

<u>To find volume of cylinder</u>

Volume V = πr²h

V = 3.14 x 1.5 x1.5 x 14 =989.1 ≈ 989 ft cube

Step-by-step explanation:

You want to solve the equation ...

... f(x) = 11

... 2x + 5 = 11

... 2x = 6 . . . subtract 5

... x = 3 . . . . .divide by 2

The value of x that makes f(x) = 11 is 3.
