Question

this cylindrical fish tank has a height of 38 inches and diameter of 26 inches. what is the volume of the fish tank.

Answer 1

using π as 3.14: 20165.08 cubic inches

in terms of π: 6422π cubic inches

Explanation:

» Concepts

The volume of a cylinder is how much space the cylinder can take inside of it. The formula to find this volume is πr²h, where r = radius and h = height. In addition, it's important to know that the radius is half the diameter.

» Application

We're given the radius as 13 inches (26/2 = 13), and the height is 38 inches. Now, we just have to plug in the values and simplify.

» Solution

Using π as 3.14:

• 
  `3.14*13^2*38`
• 
  `3.14*169*38`
• 
  `20165.08`

In terms of π:

• 
  `\pi *169*38`
• 
  `6422\pi`
