can u show me step  by dtep:)

anonymous · Answer

sure

anonymous · Answer

arc length = rad * angle
2 ft = 14 inch * angle
2*12 inch = 14 inch * angle
angle = 24/14 inch = 12/7 radians
this angle is in radians
we need to convert it into degress 
so for conversion, (12/7)*(180/pi)
solve it and u get 1080/11 deg or 98.2 deg

i got it now.... thanks a lot..:)

can i ask u about this??? how do u know the answer it'll be a radians or a degrees???

hero · Answer

If they give you a length to find, most likely, the answer is going to be in radians.

anonymous · Answer

bcoz its a standardnotation that
if length and arc is in inches, then angle is in radians
angle should always be represented in degrees, so need the conversion
