Answer:

a cone

Step-by-step explanation:

The 2D shape formed by the given coordinates is a right triangle with one of its legs on the x-axis. Once it is rotated around the x-axis, it will become a cone.

The radius of the cone is 0 - (-2) = 2.

The height of the cone is 6 - 2 = 4.

Câte diagonale are un poligon cu 5 laturi, dar cu 6 laturi?
CaHeK987 [17]

Your question isn't clear. But I infer this is the clear rendering of it;

How many diagonals does a polygon have with 5 sides, but with 6 sides?

Answer:

a. For 5 sides= 5

b. For 6 sides= 9

Step-by-step explanation:

Remember, this is the formula to calculate the number of diagonals of a polygon;

n (n-3) / 2 where n is the sides.

Thus,

for 5 sides= 5 (5-3) /2

= 5 (2) /2 = 10/2= 5

for 6 sides= 6 (6-3) /2

= 6 (3) /2 = 18/2= 9
