Answer:
Shape a has 1 order of rotational symmetry and 1 line of symmetry
Shape b has 2 orders of rotational symmetry and 0 line of symmetry
Rotational symmetry is how many times a shape can be rotated and look the same.
Lines of symmetry are how lines can be put through the shape to make it symmetrical or the same on both sides
Answer:
12.21ft³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, square based pyramid.
Volume of square based pyramid is expressed as
V= a²(h/3)
Given data
Perimeter p = 7.3ft
Height h= 11.1ft
Since the shape has a square base let us solve for the length of each side
Perimeter of square p = a+a+a+a
p= 4a
7.3= 4a
a= 7.3/4
a= 1.83ft
Substituting our given data we have
Volume = 1.83²(11.1/3)
V= 3.3*3.7
V= 12.21ft³
