Car:  distancec = 105 km + (90 km/hr)(3 hrs)

Cycle:  distancem = ratem(3 hrs)

Equate these 2 distances:  105 km + 270 km = ratem(3 hrs)

Then 375 km / 3 hrs = ratem = 125 km/hr    (average speed of the motorcyclist)

The height of the cylinder is h=7\ in.

The volume of the cylinder is V=63\pi \ in.^3

The volume of the cylinder is the product of area and height

\Rightarrow V=\pi r^2h\\

Insert the values

\Rightarrow 63\pi =A\times 7\\\\\Rightarrow A=\dfrac{63\pi}{7}\\\\\Rightarrow A=9\pi\ in.^2
