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
Answer: 9 on the x axis and 18 on the y axis
Answer:No friend is wrong
Step-by-step explanation: you actually get two answers. After you isolate the absolute value then you take the positive and negative number of what it's set equal too.
|3x + 8| - 9 = -5 add 9 to isolate the absolute value
|3x + 8| = 4
Now set two equations because the abosulte value has two answers.
|3x + 8| = 4. and |3x + 8| = -4
Solve these by removing the absolute value bars.
3x = -4. 3x = -12
x = -4/3. X = -4
Answer:
y = 45
Step-by-step explanation:
y = k x^2
500 = k * 10^2
500 = k*100
k = 5
y = 5*x^2
x = 3
y = 5*3^2
y = 45
Answer: -5x³ + x² + 4x + 8
Step-by-step explanation
This is a polynomial expressions of third order.
The equation
(-4x³ + x² ) + (- x³ + 4x + 8)
Adding them together according to their order, we now have
( -4x³ + (-x³) + x² + 4x + 8 )
-4x³ - x³ + x² + 4x + 8
-5x³ + x² + 4x + 8
