Tennis balls with a diameter of 2.5 inches are sold in cans of three. The can is a cylinder. What is the volume of the space NOT occupied by the tennis balls? (Assume the tennis balls touch the can on all sides, top and bottom.) Round to the nearest tenth and show all steps and reasoning.
Answer:
The space NOT occupied by the tennis balls is 12.26 cube inches.
Step-by-step explanation:
The space NOT occupied = volume of cylinder - total volume of spheres
The can is cylinder with volume = [tex]\pi[/tex][tex]r^{2}[/tex]h
where r is the radius and h the height of the cylinder
With the given condition,
r = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{2.5}{2}[/tex]
= 1.25 inches
h = 3 x diameter = 3 x 2.5
= 7.5 inches
So that,
Volume of the can = [tex]\frac{22}{7}[/tex] x [tex](1.25)^{2}[/tex] x 7.5
= 36.830
Volume of can is 36.83 cube inches.
The tennis ball is a sphere with volume = [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]
= [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](1.25)^{3}[/tex]
= 8.185
Volume of the tennis ball is 8.19 cube inches.
Since they are sold in three's, then;
total volume of the tennis balls = 3 x 8.19
= 24.57
Volume of the tennis balls is 24.57 cube inches.
Thus,
The space NOT occupied = 36.83 - 24.57
= 12.26
The space NOT occupied by the tennis balls is 12.26 cube inches.

Answer:
Y=(1/2)x + 3
Step-by-step explanation:
The equation of the line is y = (1/2)x + 3.
We have,
The equation of a line is written as:
y = mx + c
Where m is the slope and c is the y-intercept.
Now,
From the line,
We have the following coordinates:
(2, 4) and (4, 5)
Now,
Slope.
m = (5 - 4) / (4 - 2) = 1/2
And,
(2, 4) = (x, y)
Substituting.
y = mx + c
4 = (1/2) x 2 + c
4 = 1 + c
c = 4 - 1
c = 3
Now,
y = (1/2)x + 3
Thus,
The equation of the line is y = (1/2)x + 3.

Please I need help on this anyone
Answer:
98
Step-by-step explanation:
with the rule "corresponding angles are equal" it means that "d" and "f" are equal.
and since "f" is on the other side of 82, on a straight line, you can calculate "f".
82 and "f" would have to add up to 180' since they are on a straight line.
So you do 180 - 81 = f
and get 98.
and since "f = d"
d = 98 degrees

Answer:
[tex]a=9[/tex]
Step-by-step explanation:
In this problem, you can use the Pythagorean Theorem ([tex]a^{2} +b^{2} =c^{2}[/tex]) to find what a is. The steps are shown below:
Steps (variables a, b, and c are in italics):
-You can rearrange the formula from the Pythagorean Theorem, which is[tex]a^{2} +b^{2} =c^{2}[/tex] to only get a because we want to know what a is.
Rearranged: [tex]a=\sqrt{c^{2}-b^{2} }[/tex] or [tex]a=-\sqrt{c^{2}-b^{2} }[/tex] It has to ways/options for a because when finding the square root of a number, it can be either positive or negative. But in this problem, it’s going to be positive because we’re finding the length of something.
-Since we know what c and b are, you can plug them into the new formula:
[tex]a=\sqrt{15^{2}-12^{2} }[/tex]
-Simplify it:
[tex]a=\sqrt{225-144}[/tex]
-Subtract inside the radical:
[tex]a=\sqrt{81}[/tex] Then simplify it to get [tex]a=9[/tex].
You can check your answer by putting a back into the original Pythagorean Theorem formula ([tex]a^{2} +b^{2} =c^{2}[/tex]):
Steps
-Plug a, b, and c into the formula [tex]a^{2} +b^{2} =c^{2}[/tex]:
[tex](9)^{2} +(12)^{2} =(15)^{2}[/tex]
-Simplify to get:
[tex]81+144=225[/tex]
-Add:
[tex]225=225[/tex] This is very true. So our answer is correct.
ANSWER: [tex]a=9[/tex]
Sorry for the long explanation, but I hope you understand and that this helps with your question! :)
Answer:
a = 9Step-by-step explanation:
lets make is short and simple
Pythagorean theorem: a² + b² = c²
a² + 12² = 15²
a² = 15² - 12²
a = √81
a = 9
Point P is the center of the circle in the figure above. What is the value of x?
Answer:
x = 80°
Step-by-step explanation:
To find x, we need to create an equation.
Recall that the sum of all the 4 interior angles of a quadrilateral = 360°.
Therefore:
m<B + m<A + m<C + m<P = 360°
m<B = 20° (given)
m<C = 20° (given)
m<A = ½*x = x/2 (inscribed angle theorem)
m<P = (360 - x)°
Plug in the values and solve for x
[tex] 20 + \frac{x}{2} + 20 + (360 - x) = 360 [/tex]
[tex] 20 + \frac{x}{2} + 20 + 360 - x = 360 [/tex]
Collect like terms
[tex] 20 + 20 + 360 + \frac{x}{2} - x = 360 [/tex]
[tex] 400 + \frac{x}{2} - x = 360 [/tex]
Subtract 400 from each side
[tex] 400 + \frac{x}{2} - x - 400 = 360 - 400 [/tex]
[tex] \frac{x}{2} - x = -40 [/tex]
[tex] \frac{x - 2x}{2} = -40 [/tex]
[tex] \frac{-x}{2} = -40 [/tex]
Multiply both sides by 2
[tex] \frac{-x}{2} \times 2 = -40 \times 2 [/tex]
[tex] -x = -80 [/tex]
Divide both sides by -1
[tex] \frac{-x}{-1} = \frac{-80}{-1} [/tex]
[tex] x = 80 [/tex]

Evaluate (27)-2
-2/3
Express your answer as a fraction in simplest form.
The solution is
Note: The expression you have written sounds a little unclear, but I am assuming your expression is (27)-2-2/3.
So, I am solving the question based on assuming the expression as (27)-2-2/3, which would still clear your concept.
Answer:
The expression in the simplest form is:
[tex]\left(27\right)-2-\frac{2}{3}=\frac{73}{3}[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(27\right)-2-\frac{2}{3}[/tex]
simplifying the expression in the simplest form
[tex]\left(27\right)-2-\frac{2}{3}[/tex]
[tex]=25-\frac{2}{3}[/tex]
[tex]=\frac{25\cdot \:3-2}{3}[/tex]
[tex]=\frac{73}{3}[/tex]
Thus, the expression in the simplest form is:
[tex]\left(27\right)-2-\frac{2}{3}=\frac{73}{3}[/tex]
