Question

I 그

If minor arc AB measures 97 inches, what is the length
of the radius of circle C? If necessary, round your
answer to the nearest inch.
O 6 inches
O 12 inches
O 18 inches
O 24 inches

Answer 1

The correct option is (b).

Explanation:

Given that,

The length of the minor arc = 9 inches

We need to find the length of the radius of circle C.

Let the angle is 0.75 radians.

So,

Radius,
`r=(l)/(\theta)`

Put all the values,

`r=(9)/(0.75)\\\\r=12\ inches`

So, the radius is 12 inches.
