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

How do you find the area of the sector of the circle with a radius of 4in and a central angle θ of pi/3? Please explain procedur

Lena [83]

It is generally useful to use the formula. The procedure is to substitute the given values for the variables in the formula, then do the arithmetic.

... A = (1/2)r²·θ . . . . r is the radius, θ is the central angle in radians

Put the numbers in ...

... A = (1/2)(4 in)²·(π/3)

... A = 8π/3 in² ≈ 8.37758 in²
