Write the conversion factor for converting meters to centimeters
posledela
Since we are converting meters to centimeters we are converting large to small.

Expect the answer to be a larger number.  Here are some example of large to small:
2 weeks (larger unit) = 14 days (smaller unit)   14 is larger than 2
4 days (larger unit )  = 96 hours (smaller unit)  96 is larger than 4
Since there are 100cm in a meter, when we change meters to cm, we need a bigger number.  The conversion factor is 100 and should be used as a multiplier.
Example:  47m x 100 = 4700 cm

Please help. I don’t understand how to do this
Rasek [7]

Greetings from Brasil...

Let's apply the given formula:

A = (1/2)·B·H

The base of this polygon (in this case, the triangle) is B

B = X² - 2X + 6

The height of this polygon is H and is H

H = X + 4

Applying these values (B and H) in the given formula.....

A = (1/2)·B·H

A = (1/2)·(X² - 2X + 6)·(X + 4)

A = (1/2)·(X³ + 2X² - 2X + 24)

A = (X³/2) + X² - X + 12

OR

A = (X³ + 2X² - 2X + 24)/2

Volume of sphere:

(4/3) × 3.15 × 15³

14130 inches³

Difference:

27000 - 14130

12870 inches³
