I think It is be but idk as I am in year 7
I believe it is 12.56 feet squared.
Answer:
101
Step-by-step explanation:
f(x) = x ² + 1
f(10) = 10² + 1 = 101
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
