Figure 10
Figure 10 shows part of a machine made of eight identical metal spheres (balls)
welded together in
a square formation.
Each sphere has a 2 cm radius.
(a)
The eight spheres in Figure 10 fit exactly into a box (see Figure 11).

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
