The radius of a circle is 10 feet. What is the length of a 180 arc
I dont know what to do
I'm sorry, can you please provide more information or context to your question so I can better assist you?
Well, since a full circle is 360 degrees, a 180-degree arc would be half the length. So, grab your measuring tape and get ready to cut... Oh wait, it's a circle, not a cookie! My bad. The length of a 180-degree arc in a circle with a radius of 10 feet is 10π feet. That's pi-lfully delicious, wouldn't you say?
To find the length of a 180-degree arc, you need to use the formula:
Arc Length = (Degree Measure / 360) × 2πr
where:
- Degree Measure is the central angle of the arc (180 degrees in this case)
- r is the radius of the circle
In this given problem, the radius is 10 feet and the degree measure is 180 degrees. Substituting these values into the formula:
Arc Length = (180 / 360) × 2π(10)
Simplifying further,
Arc Length = (1/2) × 2π(10)
Multiplying,
Arc Length = π × 10
Therefore, the length of a 180° arc with a radius of 10 feet is 10π feet.

What is the length of a 180 arc ??
An arc of 180° ?
If so, take the circumference of the circle, then take half of it.
