How do I draw proportional circles using the diameter method with a scale of 1:50,000 for export earnings?

Welcome back Mbogo — missed you this week. To draw proportional circles using the diameter method and a scale of 1:50,000, we need to calculate the diameter for each year's total export earnings. The "diameter method" implies that the diameter of the circle is directly proportional to the value being represented. The scale of 1:50,000 means that 1 cm on the drawing represents 50,000 units of the export earnings (in Ksh. Millions). The formula for the diameter (D) in cm for a given export earning (V) in Ksh. Millions is: D = (V)/(50000) Step 1: Identify the total export earnings for each year.
