The area of a circle is represented by the equation:

We know that the diameter is two times the radius: 
So if we know that the diameter of the circle is 24m, we can divide this by two in order to get the radius:
-->
So then we can plug this radius in to the equation for the area of a circle:


We are told to use 3.14 as pi, and not pi itself, so let's plug in 3.14 for pi:


Now we know that the area of this circle is 452.16 square meters.
All you have to do is multiply the l * w = Area
When you look at 26 ft and 15 ft, 21 ft and 10 ft, 29 ft and 18 ft, you'd know it wouldn't work since it's over 180.
So the dimensions of the ceiling are l = 20 ft; w = 9 ft
Answer:
0 real # solution
Step-by-step explanation:
b^2-4ac<1 is equal to 0 real number solution and
-5(2+1)=-22+10
-5(2+1)=-12
which is less than 1
42,600 - 25,800 = 16800. That is the increase in 15 years.
You then calculate the increase as a percentage of the original population; 25,800.
16,800 / 25,800 * 100 = 65.11%
