The diameter of the earth

Mathematics
1 answer:
Roman55 [17]2 years ago
6 0

Answer:

25,132.74 miles

Step-by-step explanation:

Hello!

We are basically asked to find the circumference of the Earth's cross-section.

Circumference: C = 2\pi r

We can replace 2r with the diameter, because the diameter is 2 times the radius.

Multiply the Diameter by pi:

  • C = \pi D
  • C = 8000\pi
  • C = 25,132.7412287183  \approx 25,132.74

It is around 25,132.74 miles around.

vfiekz [6]
3(2x - 1) > = 4(2x - 3) - 3
6x - 3 > = 8x - 12 - 3
6x - 3 > = 8x - 15
6x - 8x > = -15 + 3
-2x > = -12
x < = -12/-2
x < = 6


the incorrect one is : A number line with a closed circle on 6, shading to the right

In the diagram shown at left, three lines intersect to form a triangle.<br> What is the value of x?
Phoenix [80]

Answer:

39°

Step-by-step explanation:

For a straight line, the sum of angle is 180°

At the point where we have the 107°, the inner angle in the triangle will be 180-107=73°

68° is alternate angle to the inner angle in the triangle

Since the sum of angles in a triangle are 180°, then angle x will be

X=180-73-68=39°

Therefore, missing angle is 39°
