Answer:

681.47 π cubic inches

Step-by-step explanation:

Given : A properly inflated basketball measures 8.8 inches across.

To Find: What is the total volume of air inside six of Jake’s basketballs?

Solution:

Diameter of ball = 8.8 inches

Radius = Diameter/2 = 8.8/2 = 4.4

Since we need to calculate the volume of air inside the ball which is in the shape of sphere

So, formula we will use

Volume of sphere = \frac{4}{3} \pi r^{3}

Where r is radius and use π =3.14

Thus the volume of air inside the ball = \frac{4}{3}*\pi *(4.4)^{3}

                                                               =\frac{4}{3}*\pi *85.184

                                                              =113.57\pi

since there are 6 balls

So, Volume of air in 6 balls = 6*113.57\pi

                                            =681.47\pi

Hence the volume of air in six balls 681.47 π cubic inches

4/3 * pi * (4.4)^3 * 6 = 8 * (4.4)^3 * pi = 681.472 * pi

The answer is : A) 681.47 * pi cubic inches

Mila [183]

Answer:

C

Step-by-step explanation:

5 1/2 pages in 12 minutes

There are 5 sets of 12 minutes in 1 hour

5 1/2 x 5 = 27 1/2

Therefore she would read 27 1/2 pages in 1 hour

Thats essentially how i did it - sorry if its not a very good explanation.

I'll assume the question is whether the tourists will all fit.
15 vans × 9 tourists each van = 135 tourists can fit so he needs another van or 5 of them have to hold on to the roof of the car

Answer:

C. Exponential

Step-by-step explanation:

If the function is linear, the differences will be equal.

d₁ = y₁ − y₀ = 4.2 − 0.6 = 3.6

d₂ = y₂ − y₁ = 29.4 − 4.2 = 25.2

d₃ = y₃ − y₂ = 205.8 − 29.4 = 176.4

d₄ = y₄ − y₃ = 1440.6 − 205.8 = 1234.8

The differences are not equal, so this is not linear.

If the function is quadratic, the differences of the differences will be equal.

d₂ − d₁ = 25.2 − 3.6 = 21.6

d₃ − d₂ = 176.4 − 25.2 = 151.2

d₄ − d₃ = 1234.8 − 176.4 = 1058.4

The differences of the differences are not equal, so this is not quadratic.

If the function is exponential, the ratios will be equal.

r₁ = y₁ / y₀ = 4.2 / 0.6 = 7

r₂ = y₂ / y₁ = 29.4 / 4.2 = 7

r₃ = y₃ / y₂ = 205.8 / 29.4 = 7

r₄ = y₄ / y₃ = 1440.6 / 205.8 = 7

The ratios are equal, so the function is exponential.
