Find the constant of proportional in the following equation y=2/3x

k =

Step-by-step explanation:

Given that y is proportional to x then the equation relating them is

y = kx ← k is the constant of proportionality

y = x ← is in this form

with k =

47

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
