for the first pic
your given width = 120yds and legnth= 53 yds
its asking how much yards did they run
so they are asking for perimeter
perimeter = 2length + 2width
perimeter = 2(120) + 2(53)
perimeter = 240 + 106 = 346yards for 1 lap
they ran 30 laps so you multiply that by 30
so 30(346) = 10380 yards is the total dist they ran
that was number 7
figure = rectangle
formula needed = perimeter
measurement to find = yards
what dimension = 120 by 53
key words= 30 laps, how many yards did the team ran
units = yards
number 8
figure = cylinder
formula need = volume of cylinder
measurement to find = cubic centimeter
what dimension = 3 dimension? <- have someone else chekc on this
key words = anything that has a number in it
units = cubic centimeter
number 4
figure = cylinder
formula needed = volume of cylinder
measurement to find = cubic inches
what dimesion= 3 dimension?
key words = anyhting that has numbers with it
units = inches
finally number 5
figure = circle
formula needed = circumference
measurement to find = feet
what dimension = 2 dimension?
key wordds = anything that has a number with it
units = feet
for 6
figure = rectangle
formula needed = area
mmeasurement to find = feet
what dimention = 2d?
key words = anything that has a number with it
units = feet
oh jayz an unsharpened pencil has a hexagon base with an area 54 mm^2 and length of 200 mm. disregarding the lead, how much wood is needed to create the pencil?

circle circumference C=pi d, since we only need half C=pid/2
total perimeter needed P= semicircle C+d = (pi*d/.2) +2.25 = (pi*2.25/2)+2.25 =---?ft.
