Aand b have the opposite directions. a has a magnitude of 7 , and b has a magnitude of 6 . what bust be true about a and b?
a) they are equal, but not parallel
b) they are opposites and parallel
c) they are parallel, but not opposites
d) they are equal and parallel

  C)  They are parallel, but not opposites

Step-by-step explanation:

They would be opposites if they had the same magnitude. As is, they are simply parallel with opposite directions.

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
