164 PointsWhy is part two of the question not letting me use float?
I dont understand what i am doing wrong, the question is to write a printf statement with a float (integer with decimal). but when i wrote it, it was bummer, %f is used for floats. I don't understand, i thought I'm suppose to use a float.

164 Pointsprintf('the radius of the ball is %f", radius);
I saw on a forum that the answer is printf("%f the radius of the ball ... but why is the %f at the beginning rather than there is needs the number to be?

719 Pointsfloat radius = 14.5; printf("A ball with a radius of %f", radius); this is your answer

164 Pointsright, I wrote that but it said it was incorrect. but it took the answer: float radius = 14.5; printf("%f A ball with a radius of 14.5 inches", radius);
Why is this one the correct form but mine is wrong?
