How much string would you need to go around the bottom of a hat shaped like a cone if the radius is 4 inches? (use 3.14 for π)

25.12 inches

Step-by-step explanation:

The amount of string that would go around the bottom of a cone-shaped hat would be the circumference of the circle.

The circumference of a circle is given by the formula

C = 2πr

Using our information, we have

C = 2(3.14)(4) = 25.12 inches

three-fourths of an hour

36÷48=0.75

0.75=

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
