Question

A circle has a radius of 47.2 units. Find the length of an arc intercepted by a central angle measuring 5.9 radians.

Answer 1

how many 5.9s are in 2pi r ?

Answer 2

what? @amistre64

Answer 3

yeah, im trying to see if im reading it right ....

Answer 4

2pi r is the length of an arc that is formed from an angle of 2pi radians

so "radians" times "radius" is arc length

Answer 5

1 radian, measures the arc ength of 1 radius

Answer 6

so 5.9 radians measures out 5.9 radiuses

Answer 7

did you get 278.48?

Answer 8

eventually yes :)
