Inscribe a circle in a unit square and to r= 1000 random.

Mathematics
1 answer:
Oduvanchick [21]3 years ago
6 0

Step-by-step explanation:

area of square = 1

area of a circle in square = \pi r^2 = \pi *(1/2)^2 = \frac{\pi }{4}

bu estimate  p^ = X/n = 760/1000 = 0.76Therefore, 
[tex]\frac{\pi }{4} \approx 0.76

\pi \approx 0.76*4 =3.04

b) if n tend to infinity

\pi will approach 3.14

Solve for x<br> solve for x
Bingel [31]

Answer:

x = 18

Step-by-step explanation:

Total interior angle of pentagon: 540 degrees

(3x + 23) + (9x - 6) + 95 + 90 + (7x - 4) = 540

19x + 23 - 6 + 95 + 90 - 4 = 540

19x + 17 + 95 + 90 - 4 = 540

19x + 13 + 185 = 540

19x + 198 = 540

19x = 342

x = 18

What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth.
kari74 [83]

Answer:

We conclude that the length of LM if L(3,4) and M(1,-2) will be:

d = 6.3

Hence, option D is correct.

Step-by-step explanation:

Given

  • L(3,4)
  • M(1,-2)

Determining the length of LM

  • (x₁, y₁) = (3, 4)
  • (x₂, y₂) = (1, -2)

The length of the distance between (x₁, y₁)  and (x₂, y₂)  can be determined using the formula

d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)

   =\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}

   =\sqrt{2^2+6^2}

   =\sqrt{4+36}

   =\sqrt{40}

   =\sqrt{4\times 10}

   =\sqrt{2^2\times \:10}

   =2\sqrt{10}

   =6.3

Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:

d = 6.3

Hence, option D is correct.
