What are the characteristics of a polygon
mel-nik [20]

Answer:

A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides. Circles and shapes that include curves are not polygons - a polygon, by definition, is made up of straight lines.

What eqauls to 31.25
RSB [31]

125 = 5^3 = 25 * 5

4 \cdot \sqrt{125} = 4 \sqrt{25 \cdot 5} = 4 \cdot 5 \sqrt{5} = 20\sqrt{5}

The simplification you are trying to do involves finding the prime factorization of a number. Since 125 is not divisible by 2, move on to 3. 125 is also not divisible by 3, so move on to 5. Then 125/5 = 25, and 25/5 = 5, so 125 = 5^3. The prime factorization of 125 is 5^3.

Find the arc length of a central angle of <img src="https://tex.z-dn.net/?f=%5Cpi" id="TexFormula1" title="\pi" alt="\pi" align=
denis-greek [22]

Answer:

The arc length is 2\pi inches or 6.28 inches

Step-by-step explanation:

To solve this we are using the arc length formula:

s=r\alpha

where

s is the arc length

r is the radius of the circle

\alpha is the central angle in radians

We know from our problem that the central angle is \frac{\pi }{4} and the radius of the circle is 8 inches, so \alpha =\frac{\pi }{4} and r=8in. Let's replace the values to find s:

s=r\alpha

s=(8in)(\frac{\pi }{4} )

s=2\pi in

s=6.28in
