Question

find the length of arc AB

Answer 1

You wanna solve it in radians or degrees?

Answer 2

what do u mean

Answer 3

Well do you know what radians are and how to use them?

Answer 4

i know cm , m , km

and 1 radian =pi/180

Answer 5

Well then \[\large \sf Arc=r\theta\] Just use theta in radians

Answer 6

but i have read a formula that arc=2*pi*r*\theta /(360)

Answer 7

That is if you have theta in degrees. That is why I asked at the beginning, so I would know what formula to give you. Radians is easier, but both are valid and it is your preference in which one to use

Answer 8

\(\Large \sf Arc=\dfrac{2\pi r\times \theta^{\circ} }{360^{\circ}}\)

Answer 9

which one is correct if it is not given abt radians

Answer 10

\[\large \sf 5\frac{\pi}{3} = \frac{2}{6} \pi 5\] They are both correct

Answer 11

You can use either formula and you will get the same answer, just use the theta as 60 degrees or pi/3 radians

Answer 12

thank

Answer 13

ye no prob
