    here we need not multiply the value of pi since the answer is in pi

    well they've given us a scale where 1cm = 10 ft. So if we plant the trees 4.7 cm = ? ft You basically want to change from 4.7cm INTO feet using the fact that 1cm = 10ft. Sooo since, 1cm = 10 ft 4.7cm = 10 * 4.7 ft = ? ft

    correct :) Read what i wrote carefully... we are converting cm ----> ft Therefore 4.7 cm -----> 47 ft right? :)
