Thread: Lune Area - help please.

Hi,

My name is Christo.
I am from South Africa.
I am struggling to calculate the area of a lune.
Help shall be greatly appreciated.

Two circles overlap.
Circle 1: Radius = 12.7
Circle 2: Radius = 13
Distance between centres = 7.

What is the area of the 13mm Radius lune?

Thank you and kind regards,
