Additiоnаl Hints: A. After creаting fоur 0.47'' diаmeter circles in the specified lоcations, create another four concentric 0.5'' radius circles;  B. Create the four horizontal lines at their desired location;   C. Create the two 0.56’’ radius circles to be tangent with the nearby two 0.5’’ radius (Use Circle Ttr (tan tan radius) mode)     D. Trim the unnecessary sides.     E. Create the two 3.00’’ radius circles to be tangent with the nearby two 0.5’’ radius (Use Circle Ttr (tan tan radius) mode). Move the tangent sign in the outward corners as indicated here:     F. Trim the unnecessary sides to get the final drawing. Save the file as Problem19_YourName.
