Question

What prism or other 3-dimensional shape would you use to model the tree trunk below? (Rectangular prism, triangular prism, square prism, or cylinder). If the height of the tree trunk is 13 ft and the radius is 1.5 ft, what is the volume in cubic feet? Round to the nearest tenth.

Answer 1

A cylinder,

91.9 ft^3 to nearest tenth.

Explanation:

That would be a cylinder,

Volume of the given tree trunk

= π r^2 h

= π * 1.5^2 * 13

= 91.89 ft^3.
