App description

Wafer area calculation

\(s= \frac {πa°}{360°} (R^2r^2)=0.008720°(R^2-r^2)\)

In the formula:

R——large circle radius

R——small circle radius

a - center angle

s - the area of the wafer

Usage example

Input data:

A—central angle: 45

R—small circle radius: 4

R—large circle radius: 8

S—wafer area: 20

Click "Calculate" to output data

Wafer area: 18.849
