Use the net as an aid to compute the surface area (rounded to the nearest integer) ofvthe triangular pyramid with an equilateral triangle base. a) 106 ft^2 b) 114ft ^2 c) 122ft^2 d) 130ft^2

A) 106 ft^2

Step-by-step explanation:

The total surface area is the area of the base triangular face and the three lateral faces.

The base triangular face has length of its base to be b=6 ft.

The height of this triangle is 5.2 ft.

The area of this triangle  is

to the nearest integer

The area of the three lateral face is

The total surface area is therefore 90+16=106 square feet

other answer is correct. i had used the radius of the radius somehow. a website:

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
