Shaded Parts of a Circle in Degrees
Problem Statement:
Run the program and determine how many degrees of the circle are shaded. When prompted, input the answer. Run the program again to start a new problem.
```/* Code generated by RoboBlockly v2.0 */
#include <chplot.h>
double angle;
CPlot plot;

plot.backgroundColor("#ccffff");
plot.strokeColor("black");
plot.circle(18, 18, 12);
plot.fillColor("#ff6666");
angle = 45 * randint(1, 8);
plot.arcSector(18, 18, 12, 0, angle);
delaySeconds(0.03);
printf("How many degrees of the circle are shaded? "+"\n");
printf("That is correct!");
}
else {
printf("That is incorrect. Run the program to try again.");
}

plot.label(PLOT_AXIS_XY, "");
plot.grid(PLOT_OFF);
plot.tics(PLOT_AXIS_XY, PLOT_OFF);
plot.axis(PLOT_AXIS_XY, PLOT_OFF);
plot.axisRange(PLOT_AXIS_XY, 0, 36);
plot.ticsRange(PLOT_AXIS_XY, 6);
plot.sizeRatio(1);
