Answer:
About 4.8
Step-by-step explanation:
The formula for the area is pi(r^2).
Plugging the area in to the equation, you get 72.382=pi(r^2).
Dividing both sides by pi, you get about 23.04=r^2.
Taking the square root of both sides you get about r=4.8
Answer:
Step-by-step explanation:
collect like terms ( when a negative sign crosses the equality sign it becomes positive and vice versa)
-6x + 10x=7-11
4x=-4
divide both sides by the coefficient of x
4x/4=-4/4
x=-1
Let <em>x</em> = 8.132132132... .
Then 1000<em>x</em> = 8132.132132132... .
Subtracting <em>x</em> from 1000<em>x</em> eliminates the fractional part, leaving you
999<em>x</em> = 8132 - 8 = 8124
Then
<em>x</em> = 8124/999 = 2708/333
