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)
The area of the square is 25=5x5
The height of the triangle is 4 and the length of the bottom is 5. Therefore, the area of the triangle is (1/2)x4x5= 10
The answer is 25+10=35
Sorry for my bad English
For simple interest rate,
I=P(i)t
54=900(i)(18/12)
i=54/900*(12/18)=4% annually
as sin (11pi/6) = -1/2
so
2x= 7pi/6+2npi
and
2x= 11pi/6 + 2npi
solve both of them for x and you will get your answer
