the figure below shows 13 circles of radius one within a larger circle. all the intersection occurs at points of tangency. what is the area of the region shaded in the figure inside the larger circle but outside all of the circles of radius 1

Area of a circle = pi r ^2          calculate the larger circle area ....then subtract the 13 smaller circle total area form it......
