How does the position of a digit in a number relate to its value example with decimals

Mathematics

dybincka [34]3 years ago

<span>,702 <span>=  6 thousands and 7 hundreds and 0 tens and 2 ones=  6 × 1000 + 7 × 100 + 0 × 10 + 2 × 1 =  6000  +  700  +  2.</span></span>

Above, we have written the number 6,702 in expanded form, or as a SUM of its different parts according to place value. 

The digit 6 in the number 6,702 actually has the value 6,000 and the digit 7 actually signifies the value 700. This is why our number system is also called a place value system, because the <span>value </span>of a digit (like 6 or 7 in our example)depends on its placement within the number. In other words, the digit 6 in 6702 does not mean six but six thousand, because the six is placed in the thousands' place. The place of a digit determines its value.

<span>The comma between thousands and hundreds is added as a separator for easier reading.  In some countries an empty space is used instead: 6,702 is written as 6 702.</span>

What’s the radius, circumference, and area?
Ivenika [448]

Answer:

Radius: 19 yards

Diameter: 38 yards

Circumference: 119. 32

Step-by-step explanation:

Radius

To find the radius you divide the diameter by 2 because, the diameter is a; a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.

So 38 ÷ 2 = 19

So the radius is 19.

_____________________

Circumference

To find the Circumference you need to do 2·π·19

C=2·π

2·π = 6.28

6.28 · 19 = 119. 32

Circumference is 119. 32
