D: 27.47 cm. A=b×h÷2

6.7×8.2=54.94
54.94÷2=27.47 cm

hey what can I say except your welcome.

A square fits exactly inside a circle with each vertices being on the circumference of the circle. The square has a side length
GarryVolchara [31]

Answer:

Therefore,

The value of x is 5.97 cm.

Step-by-step explanation:

Given:

Let the length of side of Square be "x" cm'.

Radius of Circle be "r"

Area of Circle = 56 cm squared

pi = 3.14

To Find:

x = ?

Solution:

We know Area of Circle is given by,

\textrm{Area of Circle}=\pi r^{2}

Substituting the values we get

56=3.14\times r^{2}\\r^{2}=17.83\\Square\ Rooting\\r=\sqrt{17.83}=4.22\ cm

We have, a square fits exactly inside a circle with each vertices being on the circumference of the circle,

Vertex Angle of a Square is 90°.

In a Circle Diameter Subtends a Right angle,

So it's Diagonal will be the Diameter,

Diagonal =Diameter

Diameter=2\times Radius

Substituting the values we get

Diameter=2\times 4.22=8.44\ cm

Therefore,

Diagonal = 8.44\ cm

Also we know that,

Length of Diagonal of a Square for side "x" is given by,

Diagonal=\sqrt{2}\times x

Substituting the values we get

x=\dfrac{8.44}{\sqrt{2}}=5.967\approx 5.97\ cm

Therefore,

The value of x is 5.97 cm.

Answer:

  • <em>Use ratios to solve</em>
  • <em>All results are rounded</em>

#1

  • 4/25 = x/ 125 ⇒ x = 125*4/25 = 20

#2

  • 8/11 = x/700 ⇒ x = 700*8/11 = 509

#3

  • 40/70 = x/450 ⇒ x = 450*4/7 = 257

#4

  • 3/12 = x/150 ⇒ x = 150*3/12  = 38
