The volume of a spherical balloon being inflated changes at a constant rate.If initially its radius is 3 units and after 3 seconds it is 6 units.Find the radius of the balloon after 1 seconds.

The surface are of a balloon being inflated changes at a constant rate.If initially,its radius is 3units sand after 2 seconds,it s5 units,find the radius after t seconds.

The surface area of a balloon being inflated, changes at a rate proportional to time t . If initially its radius is 1 unit and after 3 secons it is 2 units, find the radius after t seconds.

The surface area of a balloon, being inflated, changes at a rate proportional to time t. (i) If initially its radius is 1 unit and after 3 seconds it is 2 units, find the radius after time t. (ii) If initially its radius is 3 units and after 2 seconds it is 5 units, find the radius after t seconds.

In the above problem its displacement after 3 seconds is
