What solid is generated when a rectangle is rotated about a line.? a)rectangular pyramid b)cylinder c) rectangular prism d) cone

A solid is a three-dimensional figure obtained by rotating a two-dimensional figure around a straight line .

Different two dimensional figure give different three dimensional figure .

A cone is formed by rotating a right triangle about any line,a sphere is formed by rotating a circle .

If we look at the figure formed by rotating a rectangle around a line the three dimensional figure formed is a cylinder.

The answer is option b)cylinder .

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
