Question

A question ABOUT PARTS OF A CIRCLE

Answer 1

any ideas????

Answer 2

No

Answer 3

Do you have any ideas?

Answer 4

it's not my question i can help but i cant give the answer

Answer 5

okay so do you know what to do first???

Answer 6

arc length = radius* angle in radians
here the radius is 1
so?

Answer 7

No, I dont get what your supposed to do to get each one? Is their some formula?

Answer 8

i've just given you the formula

Answer 9

2pi*(x/2pi)=4.2 so x=4.2

Answer 10

4.2 = 1 * x
x = 4.2 radians

Answer 11

ok, well even if you have the formula how do you know where to place the pieces?

Answer 12

arc length = radius * angle in radians
its a unit circle so radius = 1
arc length is given as 4.2

so 4.2 = 1* angle in radians

Answer 13

\[S = r \theta\]

Answer 14

S = arc length

Answer 15

yes

Answer 16

And since a unit circle has a radius of 1, this is pretty straight-forward.

Answer 17

S = 1*theta
S = theta

Answer 18

well all I can say is , is that they need to find a simpler way to get the answer to this type of question

Answer 19

so for (-1,0) I got -1

Answer 20

if we take the radius of a circle and place it over the circunference taht is one radian:-
