155,055 PointsHi Birima,
\n is used if we want to add a new line. In this objective, that won't be necessary.
Within the string, we want to reference the value of the radius variable. To do that, we need a placeholder, which is also known as a formatter. Specifically, we need the formatter for a float variable, since the value we want to print is stored within a float type variable. The formatter that is used for floating point numbers is %f, and we'll write that where we want the value to be printed within the string. After that string, we'll write the name of the variable that we want to pull our value from.
float radius = 14.5;
printf("A ball with a radius of %f inches", radius);
Hope this helps!
