Answer:
25748 km
Step-by-step explanation:
The distance at which astronauts travel can be obtained by calculating the Circumference of the circle.
Circumference of a circle = 2πr ; π = 3.14
Radius = 4100 km
Circumference of a circle = 2 * 3.14 * 4100
Circumference of the circle = 25748 km
Hence, astronauts travel a distance of 25748 km
Answer: the length of the needle is 8.49 inches.
Step-by-step explanation:
The diagram of the clear cube is shown in the attached photo. From the diagram, a right angle triangle ABC is formed.
BC represents the diagonal of a face of the cube.
AB represents the the side length of the clear cube.
AB = h represents the length of the needle
To determine AB, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Therefore
AB² = 6² + 6² = 72
AB = √72
AB = 8.49
