Acylindrical well has a radius of 8 feet and a height of 13 feet what is the volume of the well use 3.14 for pie round your answer to the nearest hundred

To find the volume of a cylinder, you use this formula:
V = h

Plug in your numbers,
V = (3.14 * ) * 13

Exponents:
V = (3.14 * 64) * 13

Parentheses:
V = 200.96 * 13

Multiply:
V = 

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
