    illegal break?!?!?

    i am working on homework for my programming class which uses C. i have to make a program that calculates some simple geometry. the user chooses which shape to make calculations on. i am using a switch statement but when i try to break, it comes up as illlegal break when i compile. can anyone help? this is just part of the program

    Code:
    switch(shape)
    	case 1:
    		printf("Enter the radius of a circle(9999 to quit):\n");
    		scanf("%lf", &radius);
    
    		while(radius != 9999){
    			while(radius < 0){
    				printf("Invalid input!\n");
    				printf("Enter the radius of a circle(9999 to quit):\n");
    				scanf("%lf", &radius);
    				}
    			area = radius * radius * PI;
    			circumference = 2 * radius * PI;
    			printf("The area of the circle is %.2lf\nThe circumference of the circle is %.2lf\n", area, circumference);
    
    			printf("Enter the radius of a circle(9999 to quit):\n");
    			scanf("%lf", &radius);
    			}
    		break;
    
    	case 2:

    Is the missing opening brace after switch(shape) just a typo when you posted the code, or is it a typo in your code itself?

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
