Answer:
a)
Since the radius of the balloon increases by 5 cm every second, the amount of time passed in seconds multiplied by 5 will give us the radius at any given point in time
So, f(t) = 5t
b)
Since the surface area of a sphere is 4 (r)^2
We already have the radius of the sphere at any given time from our first equation
SA(t) = 4 (5t)²

The computation shows the radius of the circle that is inscribed in the isosceles triangle will be 3.33cm.
<h3>How to calculate the radius?</h3>From the information given, the isosceles triangle the length of a base is 10 cm and the length of a leg is 13 cm.
Let A = area of the triangle
Let S = semi perimeter of the triangle.
The radius will be: = A/S
where,
The radius will be:
= 3.33cm
In conclusion, the radius is 3.33cm.
