Question 1041512
A spherical plastic container for designer wristwatches has an inner radius of x centimeters. If the plastic shell is 0.3 centimeters thick, write an algebraic expression in terms of x that represents the volume of the plastic used to construct the container. simplify the expression.
--------
Inside radius = x cm
Outside radius = x + 0.3 cm
------
Shell = (4pi/3)*((x+0.3)^3 - x^3) cc
You can multiply that.
