Rounding Floats

I noticed that when the area of a circle with a radius of 25 was printed, there were a large amount of numbers after the Decimal Place. Is there a way you can decrease the number of numbers after the decimal?

you can change your format specifier from %f to %.2f. that would give you 2 decimal places. if you wanted 4 decimal places you would use %.4f and so on
