Answer:
2141.76 cubic inches
Step-by-step explanation:
Given that it measures 8.8 inches across a properly inflated basketball i.e. the diameter of each basketball is 8.8 inches.
So, the radius of the spherical ball is inches.
Now, a spherical solid has a volume given by .
Hence, volume of air in side each basketball is = cubic inches.
Therefore, the total volume of air inside six balls will be = 6 × 356.96 = 2141.76 cubic inches. (Answer)

Step-by-step explanation:
A triangle has three sides, and the angle measures for all three angles will add up to a total of 180°.
∠A + ∠B + ∠C = 180°
<u><em>Example:</em></u>
Find ∠C if ∠A = 60° and ∠B = 50°.
60° + 50° +∠C = 180°
∠C = 70°
