A / [ pi r^2 ]<span> = θ / [ 2pi ] </span> [ multiply both sides by pi r^2 ]
A = [ θ / 2 ] r^2 = <span> (1/2)r^2 θ</span>
Answer:
770
Step-by-step explanation:
280 divided by 4 = 70 so every year is 70 year increase
770 but it asked to round so by 2001 it increased to 770
(2, 7) are the coordinate which ordered pair is a solution to the following system of inequalities and .
<h3>What is inequality?</h3>
Inequality is defined as the relation which makes a non-equal comparison between two given functions.
we want to find which ordered pair is a solution to the following system of inequalities.
The solution of a inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the inequality is the graph of all solutions of the system.
Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality.
x = 2 and y = 7
