What is the arc length of a semicircle with a radius of 11?

The arc length of the semicircle is: , which is approximately 34.5575

Step-by-step explanation:

Recall that the length of a circumference of radius R is given by:

therefore, the arc length of a semicircle (half of the circle) would be given by half of the previous expression:

So, in our particular case of radius 11, the formula for the arc length of the semicircle becomes:

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
