Question

A snowboarder does tricks and names them by their degrees. convert their spins to radians. 

A) "I just performed a Cab540"

b) "did you see that Niki Huwlyer landed a quintuple cork 1980?"

c) "billy Morgan rocked a quad cork 1800!"

Answer 1

Multiply either 180/pi or pi/180 to the number given when converting degrees and radians. This works because 180 degrees is the same as pi and anything divided by itself equals one. Cancel out the term (degree or pi) that you want to get rid of from the equations. In this case, we are eliminating degrees, so we need the degree term (180) to be in the denominator.

 

A) 540 degrees/1 * pi/180degrees = 3pi

 

B) 1980 degrees/1 * pi/180degrees = 11pi

 

C) 1800 degrees/1 * pi/180degrees = 10pi
