A tree harvester estimates the trunk of a tree to have a height of about 36 meters and a base diameter of about 0.5 meter. The wood of the tree has a density of about 610 kilograms per cubic meter. Find the mass of the trunk. Round your answer to the nearest hundred. in kilograms

The mass of wood is 4309.65 kg.

Step-by-step explanation:

Volume of a cylinder is:

Where is the radius of base of cylinder

and is the height of the cylinder

is the diameter of base of cylinder.

A tree's trunk is in the shape of cylinder only. And we are given the following details:

Density of wood of tree = 610 kg per cubic meter

Mass of trunk = Volume density

Hence, mass of trunk is 4309.65 kg.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
