An equation in standard form looks like Ax + By = C.
Let C = 80
Take it from here.
<u>Collinear points</u>: Three points A, B and C are said to be collinear if they lie on the same straight line.
There points A, B and C will be collinear if AB + BC = AC as is clear from the adjoining figure.
In general, three points A, B and C are <u>collinear if the sum of the lengths of any two line segments among AB, BC and CA is equal to the length of the remaining line segment</u>, that is, either AB + BC = AC or AC +CB = AB or BA + AC = BC.
In other words,
<u>There points A, B and C are collinear if:</u>
(i) AB + BC = AC i.e.,
Or, (ii) AB + AC = BC i.e. ,
Or, AC + BC = AB i.e.,
I am pretty sure that to find the area of a circle, it’s pi times radius squared.
So in your situation, the formula would be p89 squared. So first, multiply 89 times 89, which equals 7921. You could leave it and say the answer is 7921 pi squared, or you could multiply 7921 by 3.14 (pi rounded), which would get you 24871.94 So the answer would either be:
1.) 7921 pi squared
2.) 24,871.94 feet squared
Hope this helps
