Can you divide the number 8,101,265,822,784 by 8 without using either long or short division?
LuckyWell [14K]
Yes. If we wanted to divide  104 by 8 we could write 104 as sum of multiples of 8 with which we are familiar:

104=80+24

then \frac{104}{8}= \frac{80+24}{8}= \frac{80}{8}+ \frac{24}{8}=10+3=13

We use the same procedure to divide the given number by 8:



First  We can "decompose" the number as a sum of multiples of 8 which we recognize easily. Then, divide each single one of them with 8.

That is 

 <span>8,101,265,822,784 = 8,000,000,000,000+100,000,000,000+1,000,000,000
</span>
+265,822,784

now decompose 265,822,784:

265,822,784=240,000,000+24,000,000+1,000,000+800,000+22,784

now decompose 22,784

22,784=16,000+6,784

decompose 6,784

6,784=6,400+384= 6,400+320+64


Thus:

 8,101,265,822,784 : 8 =(8,000,000,000,000+100,000,000,000+1,000,000,000+240,000,000
+24,000,000+1,000,000+800,000+16,000+6,400+320+64):8

=1,000,000,000,000+12,500,000,000+125,000,000+30,000,000+
3,000,000+125,000+100,000+2,000+800+40+8

=(1,000,000,000,000+12,500,000,000)+(125,000,000+30,000,000)
   + 3,227,848

=1,012,500,000,000+155,000,000+3,227,848

=1,012,655,000,000+3,227,848

=1,012,658,227,848

A cone and a cylinder have the same radius and height. The volume of the cone is 100π (pi) cubic feet. What is the volume of the
murzikaleks [220]

Answer:

The volume of the cylinder is 300\pi cubic feet.

Step-by-step explanation:

From Geometry we remember that volumes of a cone and a cylinder with the same radius (R), measured in feet, and height (h), measured in feet, are defined by the following equations:

Cone

V_{co} = \frac{1}{3}\pi\cdot R^{2}\cdot h (1)

Cylinder

V_{cy} = \pi\cdot R^{2}\cdot h (2)

The ratio of the volume of the cylinder to the volume of the cone is:

\frac{V_{cy}}{V_{co}} = 3 (3)

If we know that V_{co} = 100\pi\,ft^{3}, then the volume of the cylinder is:

V_{cy} = 3\cdot V_{co}

V_{cy} = 300\pi\,ft^{3}

The volume of the cylinder is 300\pi cubic feet.
