Answer:

Area of circle = \boxed{\sf{28.3 \: {in}^{2}}}.

Step-by-step explanation:

Here's the required formula to find the area of circle :

\twoheadrightarrow{\pmb{\sf{A_{(Circle)} =  \pi{r}^{2}}}}

  • A = Area
  • π = 3.14
  • r = radius

Substituting all the given values in the formula to find the area of circle :

{\twoheadrightarrow{\sf{Area_{(Circle)} =  \pi{r}^{2}}}}

{\twoheadrightarrow{\sf{Area_{(Circle)} =  3.14{(3)}^{2}}}}

{\twoheadrightarrow{\sf{Area_{(Circle)} =  3.14{(3 \times 3)}}}}

{\twoheadrightarrow{\sf{Area_{(Circle)} =  3.14{(9)}}}}

{\twoheadrightarrow{\sf{Area_{(Circle)} =  3.14 \times 9}}}

{\twoheadrightarrow{\sf{Area_{(Circle)}  =  28.26}}}

{\twoheadrightarrow{\sf{Area_{(Circle)}  \approx 28.3}}}

\star{\boxed{\sf{\red{Area_{(Circle)}  \approx 28.3 \:  {in}^{2}}}}}

Hence, the area of circle is 28.3 in².

Answer:

28.3 square inches

Step-by-step explanation:

Use the area of a circle to determine its area:

A=\pi r^2\\\\A=\pi(3)^2\\\\A=9\pi\\\\A=9(3.14)\\\\A=28.26\\\\A\approx28.3

Therefore, the area of a circle with a radius of 3 inches is 28.3 square inches

Answer:

OPTION 1

Step-by-step explanation:

You just basically plug in x and y values in all the equations and check if you get the same answer each time.

Option 1 is correct because when you plug in let's say the first coordinates,10 and 4  it does give you 6 which is right.

Or you can test it the other way, just plugging in x values and see if you get the right y value for it shown above in the table.

Hope this helps!
