: my problem is :a spherical balloon has a diameter of 2m when it is 2000m high. It is observed that the diameter of the balloon increases at a rate of 1cm/min as it continues to rise. At what rate is the volume increasing when the diameter is 3m? i need help.. i can't solve it.. thx
Write down the volume of a sphere then take the derivative with respect
to r. Then plug in your numbers.
