surface area of a sphere is roughly 4 times a circle with same radius
4pir^2 is area
bowling bal
r=4.2913
input
4*pi*4.2913=231.413
tennis ball
r=1.2598
input
4*pi*1.2598^2=19.944
minus them
bowling ball-tennis bball=231.413-19.944=211.469
multily that by 1.50
211.469 times 1.50=317.203
answer is $317.20 more
