Question

What is the approximate volume of a tree trunk if the trunk is 13 feet tall with a circumference of 4.5 feet?
A. 33.09 ft3
B. 21.17 ft3
C. 17.16 ft3
D. 27.14 ft3

Answer 1

The circumference of a circle is expressed as:

C = 2πr
4.5 = 2πr

Thus, r is equal to 0.7 ft.

The volume of a cylinder is expressed as:

V = πr²h
V = π(0.7)²(13)
V = 20.0 ft³
