Question

The measure theta in of in radians is?

Answer 1

The measure of θ is 5 radian.

Explanation:

Given that the formula of arc is arc = r×θ(*this is the formula using radian) where r represents radius. Then, you have to substitute the following values into the formula :

`arc = radius * θ \:`

Let arc = 10,

Let r = 2,

`10 = 2 * θ \:`

`2θ \: = 10`

`θ = 10 / 2`

`θ = 5 \: rad`

*Take note, the formula of arc using degrees is:

`arc = (θ)/(360) * 2 * \pi * r`
