Since it's half a pound you would need to find thirty percent of half a pound
He spent 1.59 + 2.69 which is equal to $4.28, which is your answer.
Answer:
1.
circumference=diameter ×pi
=(29×2)× pi
=59×pi
area= pie × radius²
=pi×29²
=841pi
2.
circumference =pi×16.5
area=pi×8.25²
3.
153.94÷pi
radius=square root of 49.00062388
=7.000044563
times by 2
=14.00008913
4.
28.27÷pi
8.998620482=diameter
divide by two to find radius
4.499310241
then square
20.24379265
then times that by pi
=63.59775026
So if I remember correctly, so it tells you that the area is 96 ft and we have to find X. We already have two of the measurements and if 96 ft is the area (total) then we have to figure out the missing measurement that will add up with the other two to equal 96 ft. So what I did was that I added up 20 ft and 16 ft= 36 ft. So then you just minus 36 ft from 96 ft to get your answer (X) so X= 60 ft
