Question 331428
The volume of a can that is 4in tall is given by the equation {{{V=4(pi)r^2}}}
 where r is the radius of the can, measured in inches.
:
Part A. Solve the equation for r. Please do not rationalize the denominator.
{{{4(pi)r^2}}} = V
Divide both sides by {{{4pi}}}
r^2 = {{{V/((4*pi))}}}
:
r = {{{sqrt(V/(4*pi))}}}
:
:
Part B. Using the equation produced from your work in part A,
 determine the radius of a can with volume of 12.56in^3. use 3.14 for pi
r = {{{sqrt(12.56/(4*3.14))}}}
:
r = {{{sqrt(12.56/(12.56))}}}
r = 1
