Hello! Remember to write complete questions in order to get good and exact answers. Here the figure is missing so I'll assume the arc measure of DBC is given in radian and you want it in degrees. By definition, an arc's measure is <em>the measure of its central angle </em>being a central angle an <em>angle between two radii in a circle</em>. Suppose that angle measures:
To find the total price, we use this equation: 42 + 0.039(42) We can make it simpler: 1.039(42) Multiply: 43.638 Because we're rounding The total price is $43.64
