Answer:

<h2>The volume of each tennis vall is 14.13 cubic inches, approximately.</h2><h2>The volume of each can is 63.59 cubic inches, approximately.</h2><h2>There are 49.46 cubic inches of empty space between the tennis balls and the cans.</h2>

Step-by-step explanation:

Givens

  • The diameter of each ball is 3 inches long.
  • They are sold in cans of three, that is, each can contains 3 tennis balls.
  • Each can has cylinder form.

First, we find the volum of each tennis ball.

Notice that they have spherical form, so their volume is defined by

V=\frac{4}{3} \pi r^{3}

Where r=\frac{d}{2}=\frac{3 in }{2}=1.5in

Replacing the radius and using \pi \approx 3.14, we have

V=\frac{4}{3}(3.14)(1.5in)^{3}=14.13 \ in^{3}

Therefore, the volume of each tennis vall is 14.13 cubic inches, approximately.

Assuming that the diameter of each ball is congruent with the diameter of the can, we have the volume of a cylinder defined by

V=\pi r^{2}h

Where, r=1.5in and h= 3(3in)=9in, because each can has three balls, and the height is the sum of all three diameters.

Replacing, we have

V=3.14(1.5in)^{2} (9in)=63.59 in^{3}

Therefore, the volume of each can is 63.59 cubic inches, approximately.

Now, notice that between the can and the tennis balls thereis empty space, because balls are spherical and cans are cylindric.

Let's find the difference between their volumes:

V_{empy}=63.59-14.13= 49.46 in^{3}

Therefore, there are 49.46 cubic inches of empty space between the tennis balls and the cans.

Answer:

Step-by-step explanation:

A) The equation for the volume of a sphere is V=\frac{4}{3} \pi r^{3}

As the diameter of each ball is 3 inches, that would mean that the radius of each is 1.5 inches.

Now we can plug our value into the equation

V=\frac{4}{3} \pi (1.5)^{3}

This would simplify to

V = 14.12716694 in^{3}

B) The equation for the volume of a cylinder is V=d\pi h

As there are 3 balls in a container and the diameter of each is 3, that would mean that the height is 9 inches

Now we can plug in our values into the equation

V = (3)(9)\pi

This would mean that this equation would simplify to

V = 27\pi in^{3}

C) To find the empty space, we must take the total volume, the volume of the cylinder, and subtract the volume of the tennis balls

This would mean that the equation would look like this

(27\pi)-(3(\frac{4}{3} \pi (1.5)^{3}))

This would simplify to

42.41150082 in^{3} of empty space.

What is the domain of the function Y equals cube root x
Sonbull [250]

Answer:

The domain of a cube root function is the set of all real numbers. Unlike a square root function which is limited to nonnegative numbers, a cube root can use all real numbers because it is possible for three negatives to equal a negative.

Scilla [17]
The rest station is the midpoint of the given coordinates:
(-20+35)/2 , for the x value  and (15+-12)/2 for the y value.

Coordinates of the rest station: (7.5, 1.5)

How far is the destination? Use the distance formula : D² = √(x1-x2) + (y1-y2)
(-55)² + (27)² = D²   D = √3754 = 61.27

Group Work 2.6 Newton's Law of Cooling states that an object cools at a rate proportional to the difference between the temperat
Airida [17]

Answer:

ΔT = ΔT0 e^-K T

As I understand Newton's Law of Cooling

ΔT at any time is the difference between the temperature and the surroundings

Originally       ΔT0 = 95 - 22   difference between 95 and room temperature

65 - 22 = 33 = 73 e^-KT      where t is time to cool to 65 deg

ln (33/73) = -KT       K = .794 / 5 = .159    where 5 is time to cool to 65 deg

40 - 22 = 73 e^-.159 T      where t is time to cool to 40 deg

18 = 73 e^-.159 T

ln (18 / 73) = -.159 T

T = 8.8 min

It would take 8.8 min for the object to cool to 40 deg C

Suppose the object cooled from 95 to 90 deg, then

ln 68 / 73 = -.159 T     and T = .45 min
