1.Gas escapes from a round ball at a rate of 4m/s.
\n" ); document.write( "Is 4 m/sec the exhaust speed of the gas? What is the size of the exhaust port?
\n" ); document.write( "The change in volume per unit of time is needed.

\n" ); document.write( " A.at what rate is the radius decreasing when the radius is equal to 10metre.
\n" ); document.write( "B.how fast is the surface area shrinking at the radius of 10m.\r
\n" ); document.write( "\n" ); document.write( "2.A circular patch of oil spread out on water increase at a rate of 6 cm^2/sec.At what rate is the area increasing when the radius is 2 cm?
\n" ); document.write( "-----
\n" ); document.write( "6 cm^2/sec, as stated.
\n" ); document.write( "
\n" );
