Question

If the length of an arc is 12pi inches and the radius of the circle is 10 inches, what is the measure of the arc?

Answer 1

θ = s/r
= 12pi/10
= 3.77 radians
measure = radians * 180/pi
= 3.77*(180/22/7)
= 216 degree

Answer 2

hey ive got that wrong
it should be
length of arc = a * c
so a = l / c
= 12pi/10
and soon as i saw you typing i realised my mistake math - thanx

Answer 3

sorry cherri

Answer 4

always welcome
