Find the Volume of the figure shown
A.314 m3
B.340.17 m3
C.1020.5 m3
D.942 m3

Step-by-step explanation

Volume of a cone=1/3πr²h

V=1/3*3.142*5²*13

=340.17

ratio is 2 : 9

the answer is three

13.5 : 3

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
