Find the total surface area of the
following cylinder:
r= 5 cm
5 cm
SA = [? ]ī cm2

Surface area = 2πrh + 2πr^2

= (2 × 22/7 × 5 ×5 + 2×22/7×25)cm^2

= (1100/7+1100/7)cm^2

= 2200/7 = 314.28571) cm^2 (ans)

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
