Types of labor used during industrial revolution

The Industrial Revolution marked a period of development in the latter half of the 18th century that transformed largely rural, agrarian societies in Europe and America into industrialized, urban ones.  

Goods that had once been painstakingly crafted by hand started to be produced in mass quantities by machines in factories, thanks to the introduction of new machines and techniques in textiles, iron making and other industries.

Fueled by the game-changing use of steam power, the Industrial Revolution began in Britain and spread to the rest of the world, including the United States, by the 1830s and ‘40s. Modern historians often refer to this period as the First Industrial Revolution, to set it apart from a second period of industrialization that took place from the late 19th to early 20th centuries and saw rapid advances in the steel, electric and automobile industries.

254.34

step-by-step explanation:

the formula for area of a circle is given by

a = pi * r^2

a = pi * 9^2

a = 81*pi

using 3.14 as an approximation for pi

a = 3.14*81

a = 254.34
