Question

PLEASE HELP

Answer 1

Answer:

Cylinder; radius = 6 in.; height = 5 in

Step-by-step explanation:

we are given

ABCD is a rectangle

and line m  bisects both sides it intersects

So, when we rotate it about line m

It forms cylinder

Since, height rectangle is 5in

so, height of cylinder =h=5in

half of length of rectangle =6in

so, radius of cylinder =r=6in

Answer 2

Answer:

Option D.

Step-by-step explanation:

A rectangle ABCD is rotated around line m which bisects sides AB and DC.

When a solid in the shape of rectangle (two dimensional structure) is rotated about a line, It forms a cylinder (three dimensional structure).

Here the sides of rectangle are given as AB = 12 in and AD = 5 in

Therefore the radius of cylinder formed will be =$\frac{AB}{2}=\frac{12}{2}=6 in.$

and height of the cylinder will be AD = 5 in.

Option D. is the answer.
