Question

pls help stuck ,A pebble is dropped into a calm pond, causing ripples in the form of concentric circles. The radius (in feet) of the outer ripple is given by R(t)=0.6t where t is the time in seconds after the pebble strikes the water. The area of the circle is given by the function A(r)=╥R^2Find and interpret (A(R(t)).

Answer 1

\[A(r(t))=A(0.6t)=\pi(.06t)^2\]

Answer 2

it tells you the area at time t

Answer 3

oh so did have the answer thought it couldnt b that ez
