Circumference of the outer circle = 2πr = 2π(6) = 12π

circumference of the outer arc = 120/360 x 12π = 12.57cm

circumference of the inner circle = 2πr = 2π(5) = 10π

circumference of the inner arc = 120/360 x 10π = 10.47 cm

Difference in length = 12.57 - 10.47 = 2.1cm (1 d.p.)

Answer: 2.1cm

Least to greatest 0.94,9.40,0.094,94.0,94.0
sertanlavr [38]
Here's an example number:
123.456
The place values are, from greatest to least:
The 1 is in the <em /><em>hundreds</em> place
The 2 is in the <em /><em>tens</em> place
The 3 is in the <em>ones</em> place
The 4 is in the <em>tenths</em> place
The 5 is in the <em>hundredths </em>place

If you have some number like 9.40 with no decimal point, shifting it will change the value. Moving the decimal one place to the right multiplies the value by ten. (94)
Moving it one place to the rigt divides it by ten. (0.94)

Here's our list from least to greatest:
94.0
9.40
0.94
0.094
