Question

A cylindrical piece of wood has a height of 12 inches and a base radius of 4 inches. A woodworker cuts the piece in half vertically through the center of its bases, as shown. Describe the shape of the cross section, and find its area. Justify your reasoning.

Answer 1

the cross section would be a rectangle as seen in the picture
the height would be the height of the cylinder and the width would be the diameter or twice the radius making the area 12 times (4 times 2)=12 times 8=96 square inches

shape is rectangle
area=96 in^2
