Surface area of s sphere = 4πx r^2

Diameter = 1/2 radius

Surface area = 4π x 12^2

Material required = 71.62 x 18.096

= $1296

the best buy, is the 4- kilogram bag of lollipops for $18.40.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
