A semi-circle from the FIBA rules is shown of the semi-circle is 1.8m, taken from the top edge of the free-throw line to the outer edge of the semi-circle. Assuming the semi-circle marking is 5cm wide, what is the length marked r, from the top free edge of the Free Throw line to the inner edge of the semi-circle?
1.8m - 5cm = 180 cm - 5cm = 175 cm = 1.75 m If I follow your question......the first sentence is missing some word(s)...
