Rosa grew 6 plants with 2 seed packets. How many seed packets does Rosa need to have a total of 9 plants in her backyard? Assume the relationship is directly proportional.

b.an increase in a causes b to decrease

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
