Answer:
8.40049 × 10^7
Step-by-step explanation:
Let x be the distance (in feet) along the road that the car has traveled and h be the distance (in feet) between the car
and the observer.
(a) Before the car passes the observer, we have dh/dt < 0; after it passes, we have dh/dt > 0. So at the instant it passes the observer we have
dh/dt = 0, given that dh/dt varies continuously since the car travels at a constant velocity.

V=hπr^2
V=(2k+1)π(3k)^2
V=π(2k+1)(9k^2)
V=π(18k^3+9k^2)
V=18πk^3+9πk^2
