Find: Radius of circle with area = 85

• Cursor to 85 on A
• Slide to π on B at cursor

Find: Diameter of circle with area = 85

• Slide right index of B to 85 on A
• Cursor to Gauge Point “c” on C

Find: Radius of circle with area = 680

• Cursor to 680 on A (on first section of A)
• Slide to π on B at cursor

Find: Circumference of circle of diameter = 8

• Cursor to 8 on D
• This is the same as our first example above.
