Answer:

Natural numbers are simply positive integers.  For now, refer to the middle number (the third number), as x.  Thus, the numbers are: x - 2, x - 1, x, x + 1, and x + 2.  Simply add all these numbers to get 5x, a number that is divisible by 5.  As such, you can conclude that any 5 consecutive numbers are divisible by 5, and the quotient would be the third, or middle number.

Hope it helps :) and let me know if you want me to elaborate.

The sum of four consecutive whole numbers is 54, what are the four numbers
anastassius [24]
Let the four consecutive numbers be x, x+1, x+2, and x+3.

The sum of the four numbers is 54, therefore
x + (x+1) + (x+2) + (x+3) = 54
4x + 6 = 54
4x = 54 - 6 = 48
x = 12

Answer:
The four numbers are 12, 13, 14, and 15

Find the volume of the cylinder.Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi and round
AveGali [126]

complete question:

Find the volume of the cylinder.

Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.

Radius = 4 and height = 8.

Answer:

volume of a cylinder ≈ 402.30  unit cube

Step-by-step explanation:

The question you to find the volume of a cylinder with a height of 8 and radius of 4. The volume of a cylinder can be represented below

volume of a cylinder =  πr²h

where

h = height

r = radius

h = 8

r = 4

volume of a cylinder =  πr²h

volume of a cylinder =  π × 4² × 8

volume of a cylinder =  π × 16 × 8

volume of a cylinder = 128  π

volume of a cylinder =  128 × 3.143

volume of a cylinder = 402.304

volume of a cylinder ≈ 402.30  unit cube
