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

If the farmer has 250 feet of fencing to create a rectangular pen, define a function f that expresses the area of the field (mea
hoa [83]

Answer:

Maximum area possible

f(max)  = 3906,25 ft²

Dimensions:

a  = 62,5  ft

w  = 62,5 ft

Step-by-step explanation:

Perimeter of the rectangular fencing    P  =  250 feet

And sides of the rectangle  a  and  w (width of rectangle)

Then

A =  a*w

2a  + 2w  = 250       ⇒  a  =  (250 -2w)/ 2    ⇒  a = 125 - w

f(w)  =  (125  - w ) *w        f(w)  = 125w - w²  

Taking derivatives both sides of the equation

f´(w)   =  125  - 2w              f´(w)   = 0           125  - 2w = 0

w = 125/2

w = 62,5 ft            ⇒  a = 125 - 62,5

a = 62,5 ft

f(max)  = ( 62,5)²

f(max)  = 3906,25 ft²

7 - 7(-8 + x) = -14 + 4x How do you solve for x
Lelu [443]
First thing you need to do is distributive property and that will give you
 7-56-7x=-14+4x then combine like terms which will then give you
-49-7x=-14+4x Next get your letters on the left do that by subtracting 4x which will give you -49-11x=-14. After that you will add 49 to both sides which will give you
-11x= 35. Divide by -11 to get x=3.18
