Question

For questions 1 - 2, find the measure of the arc.

(Picture below.)

Answer 1

Do u know how to measure any arc ?
I mean the formula for measuring an arc.

Answer 2

Is it angle/360 x 2 x pi x r?

Answer 3

Length of an Arc = \(\dfrac{2\pi r\theta}{360}\)

Answer 4

So ques 1 is so easy

Answer 5

place 115 at the place of \(\theta\)

Answer 6

Okay, so for the first one, would it be:
\[115/360 x 2\pi r\]

Answer 7

115/360 x 2pi r

Answer 8

no
it is \(\large{\dfrac{2\pi r\times115}{360^0}}\)

Answer 9

got it ?

Answer 10

Would the answer be 722.566
