A semi circle is half a full circle. Find the area of the full circle and divide it by 2.
Area of a circle = pi x r ^2
R is half the diameter
Area of full circle:
Area = 22/7 x 21^2
Area = 1386 sq. Ft
Area of stage = 1386/2 = 693 square feet

Introduction</h2>
Hello! I hope you are having a nice day. My name is Galaxy and I will be helping you with this problem. We can solve this problem in 2 steps, respectively Theory and Solving.
I'll go ahead and start with the Theory.
<h2>
Theory</h2>
Before we attempt to solve the problem mathematically, we must first figure out how we're going to solve this problem.
We know that we have a line and a point, we can start by graphing the equation and point that we've received.
<h2 /><h2>
Solving</h2>
Now that we have our points plotted and our equations graphed, we can start to see that something odd is happening, the given point is on the line itself.
We can check this by inputting the points into our equation:

This proves that our point is on the line that we were given.
According to the basic rules of Euclidean Geometry, we know that parallel lines can never intersect each other and due to this there cannot be any solution to this problem.
Any other line using this point would intersect the given line, and due to this, this problem has no real solutions.
* The only line that can use these points and graph is the line provided, and that cannot work due to the lines intersecting at an infinite number of points.
Cheers,
Galaxy.
Grouping similar factors together makes this easier:
(8)(2)(10^7)(10^6) = 16(10^13) = 1.6(10^14)
Answer:
A
Step-by-step explanation:
Answer: The answer is 64.5
Step-by-step explanation: Well if tiva recieves $48 for 6 hours then u have to do 48 divided by 6 which is 8. So she is earning $8 an hour. So just add 2.5 hours to 6 which is 8.5.
