this arc contains 36 degrees and its length is 7 units what is the cicruference
To find the circumference of a circle, you need to know the measure of the arc and the radius of the circle. However, in this case, you only have the measure of the arc and the length of the arc.
The formula to find the circumference of a circle when you know the measure of the arc is:
C = (360 / θ) * L
where C is the circumference, θ is the measure of the arc, and L is the length of the arc.
In this case, the measure of the arc is 36 degrees (θ = 36) and the length of the arc is 7 units (L = 7). Plugging these values into the formula, we get:
C = (360 / 36) * 7
C = 10 * 7
C = 70 units
Therefore, the circumference of the circle is 70 units.
