Answer:
1.6 I think is your answer
It is given that
A stone is thrown into a pond, A circular ripple spreads over the pond in such a way that the radius is increasing at a rate of 2.5 feet per second.
In one second the increment in radius is 2.5 feet
After t seconds, the increment in radius is given by
The area of the circular ripple is
Substitute r(t)=2.5t, we get
The required function is
Hence the fourth option is correct.
