Angle ,radian
Length of an arc=
We have to find the radius of circle in simples form.
We know that
Where l=Length of arc
r=Radius of circle
Using the formula
units
Hence, the radius of the circle=2 units
The answer to the question
Answer:
A proportional relationship is there.
Step-by-step explanation:
Here in the table, the values of y are given corresponding to the values of x.
There are four sets of values of x and y.
We have to check whether the relationship is proportional or not.
Now, rate of change of y with respect to x will be from the first two pair of values is =
Again, rate of change of y with respect to x will be from the second two pair of values is =
And, rate of change of y with respect to x will be from the third two pair of values is =
So, the rate is always 0.75.
Therefore, a proportional relationship is there. (Answer)
