Asked by Marie Pierre
1. The volume V of a right circular cylinder is given as V = pir^2h, where r is the radius of the base and h is the height of the cylinder.
a. Express the height of the cylinder in terms of iuts volume and radius of the base.
b. Translate the equation above into a verbal statement.
2. A car takes 3 hours to travel a distance of 240 km with a speed of 80 km/h while a motorbike can cover the same distance in 4 hours if its travels at a speed of 60 km/h. Explain why the speed and the time it takes for the vehicles to travel a certain distance exhibit an inverse variation.

h = v/(pi r^2)
distance = speed * time
or, speed = distance/time
so, for a given distance, speed and time are in inverse relationship.
