If a rectangle is rotatedabout the line b, below, the three dimensions of the figure shape is cylindrical with a base circle.One of the sides of the rectangle has a length of 24 cm, Suppose that the second side has a length of x cm The perimeter of the rectangle is 76 cm, then24 + x + 24 + x = 76.2 x + 48 = 76.2 x= 76 - 48,2 x= 28,x = 14 cm, then the figure in three dimensions it is a cylinder with a base radius of 14 cm Answer: the correct option is D
