We know that
volume of a sphere=(4/3)*pi*r³------> volume of a tennis ball
for r=2.5/2-----> 1.25 in
volume of a sphere=(4/3)*pi*1.25³------> 8.18 in³
volume of 3 tennis ball=3*8.18-----> 24.54 in³
volume of a cylinder=pi*r²*h
r=1.25 in
h=2.5*3-----> 7.5 in
volume of a cylinder=pi*1.25²*7.5-----> 36.82 in³
<span>the volume of the space NOT occupied by the tennis balls=36.82-24.54
</span><span>the volume of the space NOT occupied by the tennis balls=12.28 in</span>³
the answer is
12.3 in³
1 cleaning crew = 5 offices in 6 hours
You want to find out the number of offices they can clean in 12 hours
6 (hours) is

of 12 (hours)
The opposite of

is 2
6 (hours) multiplied by 2 (opposite of

) is equal to
12
6 x 2 = 12, 12 = the number of offices you're trying to find.
Therefore, you need to multiple 5 by 2 (number that is double), so
5 x 2 = 10
The crew can clean 10 offices in 12 hours
Ur counter example would mean making that conjecture false.
x^3 > 3x + 3....subbing in 2
2^3 > 3(2) + 3
8 > 6 + 3
8 > 9....this is not true...so ur answer is C. 2
