The length of arc JL is So option c is correct.
<u>Solution:</u>
Given, from the diagram, radius of the given circle is 2 units.
And, the angle between the radius JK and KL is 125 degrees.
We have to find the length of the minor arc formed by JL
The length of arc is given as:
where is angle between radii formed by points with centre
Now the length of arc JL is:
Hence, the length of are JL is so option c is correct.

<h3>What is an exponential function?</h3>An exponential function is any function that has its constant raised to the power of an argument.
An exponential function is represented as:
Where:
- a represents the initial value
- b = 1 + r; r represents the rate
From the table we have the following ordered pair
(x,y) = {(0,72000) (3,90000)}
So, we have:
Divide both sides by 72000
Take the cube roots of both sides
Recall that:
So, we have:
Subtract 1 from both sides
Express as percentage
Hence, the monthly revenue of the business grows by 8%, monthly
