2 students equal a pair, 9 pairs equal 18 students, which leave 6 students left. that remains 3 pairs, which need 3 magnets each pair. (3*3=9) Mr. Sato needs 9 magnets.

Well, a pair of students means two. if there are 24 students then there are: 24/2 = 12 pairs of students.

9 pairs already got their magnets. 12 - 9 = 3 pairs still need magnets.

each pair gets 3 magnets. So he needs 3*3 = 9 more magnets

Mathematics

A = pi * r^2

= pi * (2x^-3)^2

= pi * 2^2 * (x^-3)^2

= pi * 4 * (x^-6)

= 4*pi * x^-6
