Which answer is an example of the associative property? O 3 + 8 + 4 = 3 x (8+ 4)
O 3 + 8-4 = 3 - 8 + 4
3+ (8 + 4) = (3 + 8) + 4
O (3 + 8 + 4) = ( 3 + 8) + (3 + 4)

answer is 67%

step-by-step explanation:

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
