Rectangle ABCD has a perimeter of 32 units and will be rotated about line k.

What is the three-dimensional solid created?

cylinder

What is the radius of a base?

10 units

Check below

Step-by-step explanation:

1) Check the rectangle below with a line k, the axis of rotation in the center of the figure.

2) Since it has a perimeter of 32 units and it is to be rotated about the line, the solid to be created it is a cylinder. As you can see below.

3) Let's calculate its radius, based on the information given, i.e. the perimeter:

Since the line of rotation is the center, and the radius is half the line segment of the basis, then the radius is 5.

2/5
