What is the lateral area, total area, and volume of a regular triangular pyramid if the sides are 4

Basically, you are looking for the area and volume of a tetrahedron.
Tetrahedron area = sq root (3) * edge^2
Tetrahedron area = 27.7128129211

Tetrahedron volume = [sq root (2) / 12] * edge^3
Tetrahedron volume = 0.1178511302 * 64
Tetrahedron volume = 7.5424723327

I don't know exactly what you mean by the "lateral area".  I'm guessing it is the area of each face?
If that's the case then it equals 27.7128129211 / 4 = 6.9282032303

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
