4 generations.

Explanation:

The American pioneers were people who in different periods of history moved westward, settling in the new territories of the United States with the objective of populating the region, consolidating American sovereignty through the creation of new urban centers. In turn, the federal government promoted this migration to the west to precisely establish new inhabitants in the face of potential invasions by foreign nations. This situation, which began in the 1800s, was fully consolidated in the 1900s, that is, 4 generations later, with the western United States completely incorporated into the nation.

the berlin blockade was an international crisis that arose from an attempt by the soviet union, in 1948–49, to force the western allied powers (the united states, the united kingdom, and france) to abandon their post-world war ii jurisdictions in west berlin. in march 1948 the allied powers decided to unite their different occupation zones of germany into a single economic unit. in protest, the soviet representative withdrew from the allied control council. coincident with the introduction of a new deutsche mark in west berlin (as throughout west germany), which the soviets regarded as a violation of agreements with the allies, the soviet occupation forces in eastern germany began a blockade of all rail, road, and water communications between berlin and the west. on june 24 the soviets announced that the four-power administration of berlin had ceased and that the allies no longer had any rights there.

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
