circumference of a cylinder = 2 π R = 176 cm
Length of trunk = 3 meters = 300 cm
Radius of the cylindrical shape of the trunk of tree = R = 176 /2 π
R = 28.01 cm
Volume of the tree trunk is = Area of cross section * Length of the trunk
= π R² * L = π * 28.01² * 300 cm³
= 739497.52 cm³
= 0.739 meter³
Length of trunk = 3 meters = 300 cm
