Question

Can anyone help me with this??

Answer 1

\[L = R \times \theta\]
L = 80,
R = Radius of arc
Theta =80 degrees
\[R = L/\theta = 80/80\times180\div pie = 180/pie\]
pie = 3.141......

Answer 2

ummm but im getting different answer..

Answer 3

80/80(180/pi)
1/ 180/pi
1 x pi/180
0.01745..

Answer 4

is this correct @Mertsj ?

Answer 5

hang on.

Answer 6

sure..

Answer 7

80/360(2pir)=80

Answer 8

r=80(360/80)(1/2pi)=360/(2pi)=180/pi

Answer 9

Wouldn't that be it?

Answer 10

ummm so r=57.29578?

Answer 11

where did u get 2pi from?

Answer 12

Well yes except for the fact that the directions said leave it in the form N/pi

Answer 13

It's part of the formula for the circumference of a circle.

Answer 14

\[C=2 pi r\]

Answer 15

We know that 80/360 of the circumference is 80 in your problem.

Answer 16

ohh okay gotch ya.. thanks :)
