An equilateral triangular pyramid is spread to form the net shown here. what is the surface area of this triangular pyramid? a. 36.4 m2 b. 42.25 m2 c. 54.4 m2 d. 72.8 m2 e. 80.2 m2

ANSWER

The Correct answer is 72.8

EXPLANATION

Since the equilateral triangular prism has 4 faces, we multiply the area of one of the faces by 4 to obtain the total surface area of the prism.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

step-by-step explanation:

a.)the line for function b is steeper
