Answer:

When we have a circle of radius R, we have that the total perimeter of the circle is equal to:

P = 2*pi*R

Now, if we have an arc, this is only a section of the total perimeter, the measure of the arc is equal to:

A = (θ/2*pi)*2*pi*R = θ*R

You can see that when θ = 2*pi, the term in the left is equal to 1 and we have the complete perimeter.

Now, we have that the measure of the arc AB = 72, then we can find the angle as:

A = 72 = θ*R

then we solve this for theta:

72/R = θ

Where you can see that as bigger is the radius of the circle, smaller is the value of theta.

Remember that this equation works with angles in radians.

Answer:

108

Step-by-step explanation:

the answer would be 108. 72+108=180, and the circumference of a circle is 360. the other half equals 180, so 180+180=360.

Sorry if i'm bad at explaining...

On which number line do the points represent negative seven and one over two and +1?
MaRussiya [10]
A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers.
