$f(x) = \dfrac{4x - 3}{7}$

$y = \dfrac{4x - 3}{7}$

$x = \dfrac{4y - 3}{7}$

$7x = 4y - 3$

$7x + 3 = 4y$

$4y = 7x + 3$

$y = \dfrac{7x + 3}{4}$

$f^{-1}(x) = \dfrac{7x + 3}{4}$

A baseball has a 45 cm diameter. what is the volume of the contents of the ball

Morgarella [4.7K]

First you need to find the radius. To do that you need to divide the diameter by two;

45 / 2 = 22.5

Then you plug the radius in the formula for a sphere. Which is...

V = (4 / 3)πr^3
First you need to find the volume with out pi

V = (4/3) π (45)^3
V= π (4/3) (91,125)
Your answer with out pi is...
V= (68,343.75) π cm^3
And with pi is...
V = 214,708.22 cm^3
