Answer:
The conclusion is "Plane R and Plane S form a line if they intersect."
Step-by-step explanation:
Consider the provided statements.
1) If two planes intersect, their intersection is a line.
2) Plane Rand plane S intersect.
- If two points lie in a plane, then the line joining them lies in that plane.
- If two planes intersect, then their intersection is a line.
For better understanding refer the figure:
There are two planes R and S, which intersect at the line l.
Since the given two planes intersect, the using the above fact we can say that their intersection is a line.
Thus, the conclusion is "Plane R and Plane S form a line if they intersect."
Answer:
28.26
Step-by-step explanation:
To find the area of a circle you take pi times the radius squared ()
And to find the radius you divide the diameter by two.
To find the value of , we need to isolate it. In this case, we can do so by dividing it by
, and what we do to one side of the equation, we have to do to the other. So, divide both sides of the equation by
.
