task 2 states: Here is what your output should look like: A ball with a radius of 14.5 inches.

so the output needs to be "A ball with a radius of 14.5 inches". your current output is "the cirlce has 14.5 inches". you are also missing a comma after the string in printf

you need to modify the printf statement so that the output matches EXACTLY what the task asked for. if you dont provide the challenge with what its looking for you wont pass:

float radius = 14.5;
printf("A ball with a radius of %f inches", radius);
