The surface of a soccer ball consists of 20 regular hexagons (six sides) interlocked around 12 regular pentagons (five sides). See  Fig. 4.88. 

(a) If the side of each hexagon and pentagon is 45.0 mm, what is the surface area of the soccer ball? 

(b) Find the surface area, given that the diameter of the ball is 222 mm,

(c) Assuming that the given values are accurate, account for the difference in the values found in parts (a) and (b).
