Check the picture below.

now, recall, both blades are congruent, thus a = b, so c² = a² + b² -> c² = b² + b².

An exercise ball contains 4000 cubic inches of air when fully inflated. Write and graph a cubic function to model this situation

juin [17]

Answer:

r = 9.8475 in

Step-by-step explanation:

We assume that the ball is spherical.

The volume of a spherical ball is:

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

We know that:

$V = 4000in ^ 3\\4000 = \frac{4}{3}\pi r ^ 3$

Then

$r ^ 3 = \frac{3*4000}{4(\pi)}\\\\r = \sqrt[3]{\frac{3*4000}{4(\pi)}}\\\\r = 9.8475in$

Below is the graph of the cubic function
