document.write( "Question 52829: 2) The volume of a cylinder (think about the volume of a can) is given by V = πr2h where r is the radius of the cylinder and h is the height of the cylinder. Suppose the volume of the can is 100 cubic centimeters.
\n" ); document.write( "a) Write h as a function of r. Keep \"\" in the function's equation.
\n" ); document.write( "Answer \r
\n" ); document.write( "\n" ); document.write( "h(r)=100/(3.14)*r^2 is what i got but am not 100% sure\r

a.) \"V=pir%5E2h\"
\n" ); document.write( "\"V%2Fpir%5E2=pir%5E2h%2Fpir%5E2\"
\n" ); document.write( "\"V%2Fpir%5E2=h\"
\n" ); document.write( "V=100 so:
\n" ); document.write( "\"h%28r%29=100%2Fpir%5E2\"
\n" ); document.write( "b.) if r=2
\n" ); document.write( "\"h%282%29=100%2F%28pi%282%29%5E2%29\"
\n" ); document.write( "\"h%282%29=100%2F%28pi4%29\"
\n" ); document.write( "\"h%282%29=100%2F%283.14%2A4%29\"
\n" ); document.write( "\"h%282%29=100%2F12.56\"
\n" ); document.write( "\"h%282%29=7.96\"
\n" ); document.write( "h(2)=8cm
\n" ); document.write( "c. Let r=x, I can't change the x axis to r. Let h=y, I can't change that either.
\n" ); document.write( "You only need to look at the + side of the graph because you can't have a negative radius.
\n" ); document.write( "\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C100%2F%283.14x%5E2%29%29\"
