Which of these is the correct set-up to convert 100⁰ to radians?

• $100\times\left(\frac{\pi}{180}\right)$

• $100\div\left(\frac{\pi}{180}\right)$

• $100\times\left(\frac{180}{\pi}\right)$

• $100\div\pi$

To convert to degrees, multiply by 180 over π.

• True
• False

 $\frac{7\pi}{6}\cdot\frac{180}{\pi}=\frac{7\pi}{\pi}\cdot\frac{180}{6}=$  as an exact answer is:

• 210

•  $210\pi$  
  

• 280

• none of these

If you split the circle into 4 equal parts, how many radians will each section be?

• $\frac{\pi}{4}$

• $\frac{\pi}{2}$
  

• 45^o

• 90^o
