Question

Find the arc length of a central angle 300 degrees in a circle whose radius is 2 inches?
A.10 π/ 3 in
B.1200 in
C. 22 π/ 3 in
D. 75 in.

Answer 1

which one do you think its the asnwer?

Answer 2

Either a or c

Answer 3

okay @ShadowLegendX

Answer 4

i this one i need to check to make sure what i have is right before i can post it

Answer 5

\[\theta = \frac{s}{r}\]\[s= r\theta\]change \(\theta\) to radians. \[\theta =300^{\circ} \cdot \frac{\pi}{180^{\circ}} = \frac{5\pi}{3}\]\[s=\left(\frac{5\pi}{3}\right)(2)\]

Answer 7

so A?

Answer 8

@Jhannybean

Answer 9

use the ratio: angle / 360 = arc length/2*pi*r
you are given the angle 300 and the radius, r = 2

Answer 10

yes A
