In a circle of radius 3, the length of the arc that subtends a central angle of 320 degrees is______?
-
The entire circumference = 2 (pi) r = 6 (pi)
320 degrees is 320/360 of a circle, which reduces to 8/9 of the whole circumference
So the length of arc is 8/9 times 6(pi) = 48 (pi)/9 = 16(pi)/3
320 degrees is 320/360 of a circle, which reduces to 8/9 of the whole circumference
So the length of arc is 8/9 times 6(pi) = 48 (pi)/9 = 16(pi)/3
