London has a population of 2x10^4 and new york has a population of 6x10^5. find which population is bigger and by how much.

 New York population is bigger by 580,000 ,which can be written in standard form as 5.8 x

Step-by-step explanation:

2 x can be written in ordinary number as 20,000

6 x can be written in ordinary number as 600,000

With this , it is clear that New York has a larger population.

The difference in their population will be

600,000 - 20,000 = 580,000

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
