Step-by-step explanation:
Take the arc Sine of the function
Finally, Sine is a periodic function so it has two answers within the interval (0, 2 pi)
Use the identity
We know that
so using the identity
So we have two answers.
Answer:
490.1
Step-by-step explanation:
A=2πrh+2πr2=2·π·6·7+2·π·62≈490.08845
