The formula for the volume of a cylinder is V= a X h 
Where a is the are of base and h is height. The base is a circle, so a= pi r^2
471=3.14 (r^2)(6) Divide both sides by 6, then 3.14
   25   =r^2   Your next step would be to find the square root of 25
5=r  Now you know the radius of the circle, but it asks for diameter. The radius is half of the diameter, so 5 X 2= 10. Your answer would be 10

V= pi * r^2 * h
471 = 3.14 * r^2 *6
471 = 18.84 * r^2
25 = r^2
Sqrt25 = r
5 = r
D= 2*5
D= 10in

I need some help... HOW DO I DO THISSSS. NOT ASKING YOU TO DO IT JUST HELP ME
torisob [31]

so obviously first of all find three sherical objects or balls of varioius sizes to make it easier get a large medium and small sized.

then on scratch paper sketch those objects (im assuming by the looks of it you would trace them if not just draw them then take measuring tape or a ruler across to measure said object) now you arent told what units to measure in but id assume to stick with one unit either inches or cm

mesure the length across which is the circumference

now you would just have to do your calculations by finding the radius and volume and surface area

remember volume is (*units) cubed and suface area is (*units) sqared

Is 4x + the square root of y = 12 a linear function
ivolga24 [154]
I wouldn't say so, as if you rearrange that equation you get sqr root y = 12 - 4x. Then you square everything to get the value of y so you would end up with 144 - 16x^2.
Therefore, the x value has a power, so it would be a curved line
