Solving Situational Problems Involving Converting Degree Measure to Radian
Siužetinės Linijos Tekstas
- Angles are useful in our daily life, so it’s important to learn and understand them. Measurement as well. From home to school and store to office everywhere we use measurement.
- Why did we go to math? you know I'm weak when it comes to that but because you are my DARLING, I will try to give listen about that.
- By the way darling that u mention a CD, I have some info that I want to share with you that I learn about my trigonometry class.
- its about analyzing a revolution of CD player and we all know that CD players consistently pin at the same rate. Assume a player rotates at 480 rotations per minute. In 4 seconds, how many degrees will a point on the edge of a CD move?
- 11, 520 degrees ??
- The player revolves 480 times in one minute, or 480/60 times = 8 times every second (because 60 seconds equals one minute). The player will revolve 4 x 8 = 32 times in 4 seconds. Each revolution is 360 degrees, hence a point on the edge of the CD will rotate 32 x 360 degrees = 5760 degrees in 4 seconds.
- CORRECT DARLING, your so smart, how did you get the answer ?
- The helicopter rotates 720 times in 1 min, or 720/60 times = 12 times per sec (since 60 sec = I min). in 2 sec, the helicopter will revolve 2 x 12 = 24 times. Each revolution is 360 degrees, so in 2 sec a point on the edge of the propeller will revolve 24 x 360 degrees = 8640 degrees.
- I am expecting that I have reward later.
- what if a helicopter rotates 720 times per min. Find the degree point on the edge of propeller will rotate in 2 sec.
- Nice job darling, I am really impressed !!
- The electric fan rotates 2100 times in 1 min, or 2100/60 times = 35 times per sec (since 60 sec = I min). in 1 sec, the electric fan will revolve 1 x 35 = 35 times. Each revolution is 360 degrees, so in 1 sec a point on the edge of the fan will revolve 35 x 360 degrees = 12600 degrees
- Of course because you are my trigonometry teacher in senior high school HAHAHHAHHAHAHA.
- Sure darling if you guess the right answer in this last question. A electric fan rotating 2100 times per min. Through how many degrees does a point on the edge of the fan move in a sec.
- CORRECT, IM SO PROUD OF YOU DARLING, YOU REALLY IMPROVE, JUST KEEP GOING
