To calculate:Theshaded area if each small

Answer to Problem 35RP
The shadedarea is
Explanation of Solution
Given information:
Five circles are tangent.
Each small circle has a radius of
Formula used:
Area of a circle:
r = radius of circle.
Calculation:
To find the radius of longer circle, draw a square to connect the centers of the four small circles.Then connect the center of longer circle with the center of two smaller circles to form
Right
Hypotenuse = 6, each leg
Radius of smaller circle = 3,
Radius of larger circle
Area of longer circle:
Area of smaller circle:
Shaded Area = Area of longer circle - 4( Area of Smaller circle)
Shaded Area
