insens350 [35]
Add 0.5 to each side so you have fabric for the seams and your new numbers are 3 ft and 4 ft

find the area by multiplying 3*4 and get 12 ft

1 yard = 3 feet

12/3= 4 yards

You would need 4 square yards of fabric

Lets get started :)


The First question:
Diameter = 20 ft
Radius = \frac{1}{2} of 20 (diameter) = 20 ft

Area formula of a circle is
A = \pir²
    =\pi(10)²
    =100\pi ft²
    ≈ 314 ft²

The answer will be the second option

The Second question:
radius of circle = 12mm  divided into 20 sectors area

A = \pir²
   = \pi(12)²
   = 144\pi ft²

Divide into 20 equal sector areas = \frac{144 \pi }{20} = 7.2 \pi

≈ 22.6 mm²

Your answer will be the third option

The Third Question:

90°, sector area = 36\pi , Radius = ?

\frac{angle}{360} = \frac{sector}{ \pi (r)^2}
\frac{90}{360} = \frac{36 \pi }{ \pi r^2}
\pi and \pi cancels out

We can now cross multiply
360 × 36 = 90r²
12960 = 90r²

Divide by 90 on either side

\frac{12960}{90} = \frac{90r^2}{90}
144 = r²

Take squareroot 
 \sqrt{144} = x
x = 12 in

Your answer will be the third option

How can you inscribe a regular polygon in a circle?
dalvyx [7]

Answer:

For a shape to be inscribed means that it's area is smaller than that of the other shape. Essentially, it's one shape inside another.

View my crudely drawn example for visualization. There, the square-ish shape is inscribed in the circle.

(You can basically inscribe any shape within another.)
