The volume of ball is 113.04 cubic centimeter
<em><u>Solution:</u></em>
Given that we have to find the volume of tennis ball
Since the ball is of sphere shape, we can use the sphere formula
<em><u>The volume of sphere is given by formula:</u></em>

Where, "V" is the volume and "r" is the radius
Given that,
Diameter = 6 cm
Therefore,

<em><u>Substituting in formula, we get</u></em>

Thus volume of ball is 113.04 cubic centimeter
Answer:
At price 3 and 11, the profit will be $0
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>
A certain companies main source of income is a mobile app. The companies annual profit (in millions of dollars) as a function of the app’s price (in dollars) is modeled by P(x)=-2(x-3)(x-11) which app prices will result in $0 annual profit?</em>
My answer:
Given:
- x is the app price
- P(x) is the profit earned
If we want to find out the app price that will result in $0 annual profit? It means we need to set the function:
P(x)=-2(x-3)(x-11) = 0
<=> (x-3)(x-11)= 0
<=> x - 3 = 0 or x - 11=0
<=> x = 3 or x = 11
So at price 3 and 11, the profit will be $0
Hope it will find you well.
