## Trigonometry (10th Edition)

$9360^{\circ}$
1.Given 650 rotations per minute, change it to degrees per minute by multiplying by 360 degrees $650\times 360=234000^{\circ}$per minute 2. Devide by 60 to find degrees per second $234000 \div 60 = 3900^{\circ}$ per second 3. To find rotations in 2.4 seconds, multiply by factor 2.4 $3900\times 2.4 =9360^{\circ}$
