Please enter the surface area. Will mark brainliest if correct​
Vitek1552 [10]

Answer: 3668.94 m^2

Step-by-step explanation:

35.7 * 15.1 = 539.07

35.7 * 15.1 = 539.07

25.5 * 15.1 = 385.05

25.5 * 15.1 = 385.05

35.7 * 25.5 = 910.35

35.7 * 25.5 = 910.35

539.07 + 539.07  + 385.05  + 385.05   + 910.35  +  910.35  = 3668.94

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>
