Breaking Apart Strategy is an easy way to find multiplication, even though those are difficult ones. This is a great strategy for breaking apart harder multiplication problems, so the result you get is the same as if you are multiplying the original equation.
<span>
For example, suppose you want to get this multiplication:
</span>
<span>
So eight times seven is a tricky one sometimes. Maybe we forget this multiplication so let's break it apart. Therefore, let's break apart seven, that is:
</span>
<span>
This is true because five and two makes seven. Therefore, the new equation is:
</span>
<span>
Applying distributive property:
</span>
<span>
So:
</span>
<span>As you can see the multiplication was obtained in a easy way.

Answer:
2160 square units
Step-by-step explanation:
Given data
Radius= 6 units
Angle= 120°
Area of the sector is given as
Area of sector= r^2* ∅/2
Area of sector= 6^2*120/2
Area of sector= 36*60
Area of sector= 2160 square units
Just look up equation for volume of a sphere:
V = 4/3*(pi)*r^3
r = 4.7 inches
Therefore...
V = 4/3*3.1415*4.7 = 434.9 in^3
