How Big Is The Red Area?

I was walking by the cathedral in town today and found out it was Ash Wednesday today thanks to the congregation of people sat at the front of the church, waiting for the liturgy to commence.

So out of curiosity, I took a seat and had my first ever Ash Wednesday liturgy. When the priest imposed a pinch of ash on my forehead, he said, “Remember that you are dust, and to dust you shall return. Turn away from sin, and be faithful to Christ”

I think I got a goosebump when that happened. He also looked like a wizard of some sort from some fantasy fiction. 

Later I received my first ever communion, which was a tiny circular piece of biscuit-like substance. A cross was etched in the middle of it. I gulped it down like it’s nothing because it did taste like nothing.

The songs the Lay Clerks sang were in Latin, and I was pleasantly surprised to know that I can understand some of the words thanks to my knowledge of English and French. 

Anyway, I hope you enjoy today’s math puzzle. 



Solution

So let’s take a look at this diagram I have drawn.

We want to find the red area, and that’s equivalent to the area of the circle minus 4 of those lune-like pieces.

Each of those pieces is the quarter circle take away an isosceles triangle with base and height = 1.

So our answer is 2.
