A fan has blades that spin at 50 revolutions per minute. The blades are 20 inches long. What is the angular velocity of the blades, in radians per minute? Round your answer to the nearest hundredth.
rad/min

  314.16 rad/min

Step-by-step explanation:

There are 2π radians in every revolution, so the 50 revolutions will be ...

  (50 rev/min)(2π rad/rev) = 100π rad/min ≈ 314.16 rad/min

35 is an outlier

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
