How does the area of the polygons compare to π? ( π is 3.14)
soldi70 [24.7K]

The area of the polygons compare to π in the way that as more angles and sides are added to a polygon the polygon becomes closer to a circle; the perimeter slowly changes to circumference. Π is used to find the area and circumference of a circle, so as polygons come closer to becoming circles π becomes more strongly associated to the polygon. You can even use π to find the approximate area of a circle if you use the same formula (as you would to find the area of a circle) on a polygon. Another way to go about it is like this…

You can find the area of a circle if you know the circle’s circumference by using these steps:

<span>1.         Divide the circumference by π to find the diameter of the circle.</span>

<span>2.         Divide the diameter by 2 to find the radius of the circle.</span>

<span>3.         Now that you have the radius you can use the formula Area= πr2 to find the area of the circle.</span>

Complete the proof by providing the missing statement and reasons
Lisa [10]

Answer:

In triangle SHD and triangle STD.

\overline{SD} \perp \overline{HT}          [Side]

Since, a line is said to be perpendicular to another line if the two lines intersect at a right angle.

⇒ \angle SDH = \angle SDT = 90^{\circ}

\overline{SH} \cong \overline{ST}       [leg]               [Given]

Reflexive property states that the value is equal to itself.

\overline{SD} \cong \overline{SD}       [Leg]       [Reflexive property]

HL(Hypotenuse-leg) theorem states that any two right triangles that have a congruent hypotenuse and a corresponding congruent leg are the congruent triangles.


then, by HL theorem;

\triangle SHD \cong \triangle STD                       Proved!

What is the sales tax rate?
Allisa [31]
Hello there! We are solving for the tax rate, so let's start off by subtracting both prices. 4.32 - 4.00 is 0.32. That's a 32 cent difference in the price. Now, let's divide that number by the original price to find the percentage. 0.32/4 is 0.08. Multiply that number by 100 and that is 8%. There. The sales tax rate is 8%.
