Question

a cylinder has a base diameter of 20 ft and a height of 5 ft what is its volume in cubic ft to the nearest tenths place

Answer 1

1570.0
`ft^(3)`

Step-by-step explanation:

First, you have to know the formula of the "Volume of the Cylinder." Its formula is: V (volume) =
`\pi r^(2) h`, where:

• 
  `\pi` (pi) = 3.14
• r (radius) = ?
• h (height) = 5 feet

You can get the radius by dividing the base diameter into 2. Let's solve:

• 20 feet (base diameter) ÷ 2 = 10 feet

The cylinder's radius is 10 feet.

Now that we know the radius, we can already compute for the value of the volume.

• V =
  `\pi r^(2) h`

• V = (3.14) x (
  `10^(2)`) x 5 feet
• V = 3.14 x 100
  `ft^(2)` x 5 ft
• V = 1,570.0
