<h3>❒ <u>Given</u> ❒</h3>

❖ Area of circle = 6767 sq.cm

<h3>❒ <u>To Find</u> ❒</h3>

❖ The required diameter of a circle ?

<h3><u>Solution</u> </h3>

<h3>❒ <u>Concept</u> ❒</h3>

❖ If the area of the circle is given then divide the outcome by π and find its square root in order to get the radius; then multiply by 2 to obtain the diameter.

<h3>❒ <u>We know that</u> ❒</h3>

➻ Area of Circle = πr²

➻Then radius of Circle ( r ) = √A / π

❒ Note = Here A stand for area

➻Thus diameter of Circle (d ) = 2 r

❖ Using the given formula and by solving for d ,we have ,

➻ d = 2 × √A / π

➻ d = 2 × √6767 / π

. . .( ∵ A = πr² = 6767 )

➻ d ≈ 92.82248 cm

➻ d = 92.82 cm

<h3>❒ <u>Therefore</u> ❒</h3>

❖ The required diameter of a circle is

  • ➻ d = 92.82 cm

  • Area=6767cm²

Diameter be d

Radius be r

  • πr²=6767
  • r²=6767/π
  • r²=2155
  • r=46.4cm

Diameter=2r=46.4(2)=92.8cm

The length of the garden is 10 feet more than twice its width. The perimeter of the garden is 170 feet.
kumpel [21]

Answer:

Width is 25 ft

length is 60 ft

Step-by-step explanation:

Here, we want to calculate the length and width of the garden

From the question, we are told that the length is 10 ft more than twice its width

So if the width is x ft

Length = 2x + 10

Mathematically, the perimeter of a rectangle i s 2(l + b)

So;

2(x + 2x + 10) = 170

2(3x + 10) = 170

3x + 10 = 85

3x = 85-10

3x = 75

x = 75/3

x = 25 ft

length is;

2(25) + 10 = 50 + 10 = 60 ft
