3) In the figure below, four circles are placed in contact with each other such that they are tangent to each other. If the radii of the circles C,, C, C,, and C,, are R, 16 mm, R, -6.5 mm, R,-12 mm, and R, -9.5 mm, write a MATLAB program to determine the distance between the centers, C and C, C2 C3 C4 Hint, You may have to use the Law of Cosines which for any triangle as shown below is as follows: The Law of Cosines: c+b-2ab cosy 3) In the figure below, four circles are placed in contact with each other such that they are tangent to each other.
