Answer 2

Please consider the complete question.

In circle M, diameters JL and HK each measure 16 centimeters. What is the approximate length of minor arc JH?

We will use arc-length formula to solve our given problem.

`\text{Arc length}=2\pi r\cdot (\theta)/(360)`, where,

r = Radius

`\theta` = Central angle.

We can see from the attachment that angle KML and angle JMH are vertical angles, therefore, their measure will be equal.

We can see that Jl is diameter of circle, so radius will be half of 16 that is
`(16)/(2)=8` cm.

`\text{Arc length}=2\pi (8)\cdot (25)/(360)`

`\text{Arc length}=16\pi\cdot0.06944444`

`\text{Arc length}=3.49065828`

Upon rounding to nearest tenth, we will get:

`\text{Arc length}\approx 3.5`

Therefore, the length of minor arc JH is approximately 3.5 cm and 1st option is the correct choice.
