What is the domain and range of y=-3

Domain is from where to where x can go

Range is from where to where y can go

As we know y=-3, it cannot change

Range=-3

X can be whatever and y will still be -3

Domain= (-infinity;+infinity)

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
