Question

The density of the American white oak tree is 752 kilograms per cubic meter. If the trunk of an American white oak tree has a circumference of 4.5 meters and the height of the trunk is 8 meters, what is the approximate number of kilograms of the trunk?

Answer 1

Answer:

I have given answer okay

Step-by-step explanation:

First, we determine the volume of the trunk by finding

first the radius from the circumference through the equation,

C

= 2πr

r

= C/2π

Substituting the known values,

r

= 4.5/2π = 0.716 m

Then, we calculate for the volume through the equation,

V

= πr2h

V

= π(0.716 m)2(8m) = 12.9 m3

Multiplying the calculated value to the density will give

the mass as,

Mass

= (12.9 m3)(752 kg/m3) = 9699.36 kg
