How did this diagram advance scientific thinking?
The diagram showed that planets move in circular
orbits around the sun, disproving the Copernican
model.
The diagram showed that Earth is closer to the sun
than other planets, disproving the heliocentric theory.
The diagram demonstrated the first law of planetary
motion, proving the heliocentric theory.
The diagram demonstrated the first law of planetary
motion, proving the geocentric theory.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

answer is c.

quadrilateral

hope you got it chief

im not sure what your asking ?

step-by-step explanation:

1875cm³

step-by-step explanation:

we have a 20 × 20 × 5 container with (what im guessing is a) 5 × 5 × 5 hole in the center. first, we need to calculate the volume of the 20 × 20 × 5 container.

20 × 20 × 5 = 2000cm³

now, we need to calculate the volume of the hole.

5 × 5 × 5 = 125cm³

now to find the area of the container, we take to solid area of the container, and subtract the area of the hole.

2000cm³ - 125cm³ = 1875cm³
