Answer:
see the attachment
7 hours
Step-by-step explanation:
The cost for River Y is a constant (not dependent upon hours), so is c = 41.
The cost for River Z is the sum of the deposit and the hourly cost, so is ...
c = 13+4n
These equations and their graphs are shown in the attachment. The graphs cross where n=7, indicating you have to rent a canoe for 7 hours for the cost to be the same on both rivers.
The circumference of the tennis ball is 16.177 inches so the opening of the container must be equal to or greater than the circumference of the ball.
<h3>What is the volume of the sphere?</h3>The volume of the sphere is defined as the space occupied by the sphere in the three dimensions.
In this question, we need to find out the size of the cylinder opening so
the tennis ball can fit inside the opening.
To find out this we need to calculate the circumference of the ball because if the opening of the cylinder will be equal to or greater than the circumference of the ball then the ball can easily fit inside the cylinder.
So to find out the circumference we will find the radius
Now the circumference of the tennis ball will be
Hence the circumference of the tennis ball is 16.177 inches so the opening of the container must be equal to or greater than the circumference of the ball.
