Answer:
The range of given data set is 90.
Step-by-step explanation:
We are given the following data:
20.9, 33.1, 21.8, 58.5, 23.5, 110.9, 30.4, 24.9, 74.1, 60.3, 40.4, 45.4
When this data is arranged in ascending order, we get:
20.9 , 21.8 , 23.5 , 24.9 , 30.4 , 33.1 , 40.4 , 45.4 , 58.5 , 60.3 , 74.1 , 110.9
Range is a measure of dispersion and can be easily calculated.
Formula:
Thus, the range of given data set is 90.
Answer:
answer is 24.56cm
perimeter of half/semi circle = r + 2r
<em>one semi circle semi circles perimeter: </em><em>*2+2*2 =10.283cm, </em>
<em>for two semi circles= 2*10.283 =20.566cm</em>
without the line below for two semi circle: 20.566-4-4=12.566 cm
both da side of rectangle is 6cm+6cm=12cm
now add the 12.566+12=24.56cm
