## How to Find Cubic Yards of a Circular Shapes - Tutorial

#### Definition:

This tutorial explains you how to calculate the stepping stone area for circular shape cubic yards.

#### Example :

If the diameter, depth of 5 circle stepping stone is 120 inches and 4 inches, then calculate the Circle and all stepping stone Cubic Yard values.?

d = 120 in
h = 4 in
n = 5

#### Formula:

Circle Stepping Stone = (Π X r2 X h) / 46656 Where, h = Depth in inches r = d / 2 d = Diameter in inches

#### Solution:

##### Step 1 :

First, let us calculate the radius value.

 Radius (r) = d / 2 = 120 / 2 = 60
##### Step 2 :

Substitute the given values in the formula,

 Circle Cubic Yards = (Π X r2 X h) / 46656 = (3.14 X 60 X 60 X 4) / 46656 = 0.97 cu yds
##### Step 3 :

To calculate the value of all stepping stone cubic yards multiply the above result by n =5,

 All stepping stone cubic yards = 0.97 X 5 cu yds = 4.85 cu yds
