Answer:
2g - 66
is the equation for given statement.
Let and be the respective radii of balloons A and B. If the fixed total volume is V, then
and knowing and at the start, we have V = 6916π/3 cm³. Then when , the radius of the other sphere is .
Differentiating both sides with respect to time t gives a relation between the rates of change of the radii:
We're given the whole time. At the moment , the radius of balloon B is changing at a rate of
A = πr^2
D = r • 2
R = D/2
7/2 = 3.5
R = 3.5
A = πr^2
A = 3.14 • 3.5^2
A = 3.14 • 12.25
A = 38.465
A = 38.47
So therefore the area of the circle is 38.47!
