The population of the US at the first census in 1790 was 3,929 people. By 2000 the population had increased to 284,000,000! What is the percent increase in the population?

7,228,202%

Step-by-step explanation:

Population at first census in 1979 was 3929

If the Population had increased to 284,000,000 by 2000, the population increase will be;

284,000,000-3929

= 283,996,071

%increase in population = increment/initial population×100%

= 283,996,071/3929×100%

= 7,228,202%

This means that the population has increased by 7,228,202%

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

b
