Use the arc length formula and the given information to find s. Show your work for full credit.
r = 15 ft θ = 35° s = ?

anonymous · Answer

what's the arc length formula?

anonymous · Answer

cause you should probably start there

anonymous · Answer

s = rθ where s represents the arc length, θ represents the central angle in radians and r is the length of the radius.

anonymous · Answer

Do i just plug the numbers in and solve?

anonymous · Answer

your given your angle in degrees, but your definition says the angle must first be in radians...can you convert?

anonymous · Answer

yes i can

anonymous · Answer

when converted you get 7pie over 36

anonymous · Answer

right, then that goes into the equation.
so instead of multiplying the radius (r) by a full revolution (2*pi as you would to find the circumference) your just subbing in a fraction of a complete circle
