Question

If s denotes the length of the arc of a circle of radius r subtended by a central angle \theta , find the missing quantity.

s = 7.02 meters, \theta = 2.6 radians, r = ?
a. 0.37 m
b. 3.6 m
c. 1.35 m
d. 2.7 m

Answer 1

It will be 0.37 meters.

The answer comes from the definition of radians:

\[v= \frac{s}{r}\]

When solving for r gives you 0.37m with the given radian (v), the given arc length (s).

Answer 2

I think it will be 2.7 m
What do you think?

Answer 3

Are you sure about the your answer Elek?

Answer 4

No ofc what the hell am I doing. It is wrong. Haha, it is r = s/v, I am so sorry

Answer 5

Which gives 2.7. Again, deeply sorry. It's been a messy day^^

Answer 6

Question 15
Perform the indicated operations and simplify the result. Leave the answer in factored form.
\LARGE \frac{\frac{4}{x} + \frac{7}{x^2}}{\frac{16}{x^2} - \frac{49}{x}}

a. \frac{1}{4 -7x}
b. \frac{4x^2 + 7}{16 - 49x}
c. \frac{4x + 7}{16 - 49x}
d. \frac{1}{4x - 7}
