The complete question is: Henry knows that the circumference of a circle is
18π inches. What is the area of the circle?
Solution:Circumference (C) of the circle can be written as:

Using this value of radius, we can find the Area(A) of the circle.
Therefore, area of the circle having a circumference of 18π inches will be 81π inches²
Given:
The inequality is:

To find:
The y-intercept, slope and type of line (solid or dotted).
Solution:
The slope intercept form of a line is:
...(i)
Where, m is the slope and b is the y-intercept.
We have,

The relation equation is:
...(ii)
On comparing (i) and (ii), we get


It means the slope is 5 and the y-intercept is 3.
The sign of the inequality in the given inequality is ">". It means the boundary line is not included in the solution set. So, the boundary line is a dotted line.
Therefore, the slope is 5, the y-intercept is 3 and the line is a dotted line.
Answer:
11.401754251 or the square root of 130
Step-by-step explanation:
the length squared is the area so you have to do inverse operations and do the square root
Answer:
10.5 is really 10.50 the . 5 is half the whole one unit, like 50 cents is half a dollar
