The surface area sr (in square meters) of a spherical balloon with radius r meters is given by =sr4πr2. the radius pt (in meters) after t seconds is given by =pt73t. write a formula for the surface area nt (in square meters) of the balloon after t seconds. it is not necessary to simplify.

Explanation:

It is given that,

The surface area of a spherical balloon with radius r meters is given by :

The radius P(t) (in meters) after t seconds is given by, P(t) = 73 t.

We need to write the surface area N(t) (in square meters) of the balloon after t seconds.

So, the surface area of the balloon is . Hence, this is the required solution.

this a false
