Answer:
A≅562.45π u²
Step-by-step explanation:
Knowing that the volume the a solid is V=πR²h, then A=πR², therefore
A=π(4√x), integrating on both sides ∫A=4π∫√xdx ⇒ ∫√xdx =
evaluated (60,77), then
First we can figure out an hourly rate at which cars are washed. To do so, we need to divide 5 cars by 3 hours.
Then we need to multiply 7.5 hours by the rate. This will tell us how many cars are washed in 7.5 hours.
= 12.5 cars
Then we need to multiply 7.5 hours by the rate. This will tell us how many cars are washed in 7.5 hours.
