1. Add the large and small pulley diameters together.

**10 + 2 = 12**

2. Multiply the total
amount by 1.6

(Half of 3.14 (pi) of the sum of
the two pulleys)

**12 x 1.6 = 19.2**

3. Add twice
the distance between the two shafts.

**24 x 2 = 48**

48 + 19.2 = 67.2

The total will be the
approximate belt length.

**67" belt**
