It is direct variation if x/y is a constant.

x/y = 2 / -6.6 = -1/3.3

y/x = -9.9/3 = -3.3

y/x = -6.6/ 2 = -3.3

y/x = -13.2/ 3 = -3.3

y/x = -16.2/ 3 = -3.24

So its not exactly direct variation as the last values is slightly different from the first 3.

I need help ASAP!!!!
mrs_skeptik [129]

Answer:

Step-by-step explanation:

the shape is made up of 2 circles and one box add the 3 areas up

circle area = \pir^{2}

3.14*4^{2} = 50.24

50.24*2 =100.48

box, box,  pit now  :P  ooh I was thinking formula one racing,  ( i've been watching that lately)  anyway

box = 8*8 = 64

total = 164.48  is that an option? hmm, yes the bottom two choices.. now the perimeter .  the perimeter is made up of the 2 circles

the circumference of a circle is 2\pir

2*\pi*r

2*\pi*4 =25.1327    that's one whole circle , multiplied by 2 , I can see , by math in my head that's about 50.26

sooo

the 3rd choice looks good  :)
