Suppose the volume of a tree is given by V=1c²h where c is the circumference of the tree in meters at ground level and his the height of the tree in meters. 8ள (a) Because the tree grows over time, we can assume c, h, and V are all functions of time. Find dv dt dv = dt dv dt (b) What does represent? -Select- (c) When the tree's circumference is 4 meters and its height is 15 meters, the circumference is growing at a rate of 0.2 meters per year and the height is growing at a units --- v v
