Question

The measure theta in of in radians is?

Answer 1

Answer:

The measure of θ is 5 radian.

Step-by-step 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 :

$arc = radius \times θ \:$

Let arc = 10,

Let r = 2,

$10 = 2 \times θ \:$

$2θ \: = 10$

$θ = 10 \div 2$

$θ = 5 \: rad$

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

$arc = \frac{θ}{360} \times 2 \times \pi \times r$
