Circumference of a circle=2πr
Where r is radius
C=(2*2.2)π
C=4.4π
Answer:
First table
Step-by-step explanation:
We have to find the set of value which could be from a direct proportion.
We know that
Direct proportion :
When x is directly proportional to y


Where k=Proportionality constant

K remain constant when x and y are in direct proportion
From first table




When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.
From second table
not ]define

It is not direct proportion because k does not remain constant.
From third table


It is not direct proportion because k does not remain constant.
Answer:
Step-by-step explanation:
5.1 × 108 = 550.8
9.6 × 10^0
10^0 = 1
9.6 × 1 = 9.4
2.44 × 10 = 24.4
5.023 × 1010 = 5073.23
