Aspherical weather balloon is being inflated. the radius of the balloon is increasing at the rate of 7 cm/s. express the surface area of the balloon as a function of time t (in seconds). (let s(0) = 0.) . s(t) = cm^2?

Step-by-step explanation:

We are given that

Radius of balloon increasing at the rate= 7 cm/s

Let time= t seconds

In 1 second radius  =7 cm

In t second radius =R(t) = 7 t

We have to find the surface area of  balloon as  function of time t

We know that area of sphere=S(R)=

Substitute the value

Hence,

answer: i would say b
