Y=x+2 is the correct answer:)
Diameter=16mm, so the radius is 8. The formula for volume of a cylinder is the area of the base times height, or v=πr²h.
Substituting the values in, we get π(8²)(5.7), which gives us roughly 1146mm^3.
Answer:
y = 7.5
Step-by-step explanation:
given y is directly proportional to then the equation relating them is
y = k ← k is the constant of proportion
to find k use the condition y = 75 , x = 100 , then
75 = k
= 10k ( divide both sides by 10 )
7.5 = k
y = 7.5 ← equation of proportion
