A tetrahedron is a triangular pyramid whose four faces are identical equilateral triangles. The total lateral surface area is 93
square centimeters. Find the surface area of the tetrahedron.
1 answer:
Answer:
Step-by-step explanation:
The total area is four times a face area and the lateral area is three times a face area.
Let x be the total surface area then
x/93=4/3
x=4(93)/3
x=372/3
x=124 cm^2

Step-by-step explanation:
V = A h.
Since the area of a circle = π r 2 , then the formula for the volume of a cylinder is:
V = π r 2 h.
If x>5......f(x)= x-5
if x <5......f (x)= -x+5
