we know that

Area of the circle is equal to

A=\pi r^{2}

where

r is the radius

in this problem

diameter=12\ in \\ radius=diameter/2\\ radius=12/2\\ radius=6\ in

A=3.14* 6^{2}

A=113.04 in^{2}

therefore

the answer is the option

d. 113.04 sq. in.

The area of the Frisbee is about 113 in.² ( Option D )

<h3>Further explanation</h3>

The basic formula that need to be recalled is:

Circular Area = π x R²

Circle Circumference = 2 x π x R

where:

<em>R = radius of circle</em>

The area of sector:

\text{Area of Sector} = \frac{\text{Central Angle}}{2 \pi} \times \text{Area of Circle}

The length of arc:

\text{Length of Arc} = \frac{\text{Central Angle}}{2 \pi} \times \text{Circumference of Circle}

Let us now tackle the problem!

<u>Given:</u>

Diameter of Frisbee = d = 12 in

<u>Unknown:</u>

Area of Frisbee = A = ?

<u>Solution:</u>

<em>Area of the Frisbee could be calculated using the area of circle as follows:</em>

A = \frac{1}{4} \pi d^2

A = \frac{1}{4} \times \pi \times 12^2

A = 36 \pi ~ in.^2

A \approx \boxed {113.10 ~ in.^2}

The closest option available will be option D. 113 in.²

How many solutions does this system of linear equations have? Explain. 3y + 6x = 12 8x + 4y = 16
Vilka [71]

Answer:

first equation : 3y + 6×=12

second equation : 4y + 8x = 16

Step-by-step explanation:

first equation

3y + 6× = 12

now take the common ,

3( y + 2x ) = 12

so, y + 2x = 4

second equation

4y + 8x = 16

4 ( y + 2x ) = 16

so, y + 2x = 4

two lines with same equation have infinitely many solution . these two equations are the same so there are infinitely many solution .
