Convert the radian measure to degree measure. Use the value of π found on a calculator and round answers to two decimal places.

Question

anonymous · Answer

this is the formula for converting degrees to radians: angle x pi/180
radians to degrees: radians x 180/pi

anonymous · Answer

$\large s=r\theta $ where theta is in radians...

anonymous · Answer

can you pleae show me work?

anonymous · Answer

you're looking for arclength, s, soyou need to convert 35 degrees into radians to use the formula...

anonymous · Answer

$\large s=(15feet)(35 \cdot \frac{\pi}{180}) $

anonymous · Answer

$\large s=(15feet)(35degrees \cdot \frac{\pi radians}{180degrees}) $
$\large s=(15feet)(35\cancel{degrees} \cdot \frac{\pi radians}{180 \cancel {degrees}}) $

so you end up with feet as your units.... radians is "unit-less"

anonymous · Answer

so what does s=?

anonymous · Answer

convert degrees to radians:
35 x pi/180= 7/36pi
then, multiply this by 15 ft to get s:
7/36pi x 15 ft= 35/12pi= 9.2
