Answer:
The diameter of the circle would be: 6.4 cm. rounded or 6.36619772 cm.
The radius of the circle would be: 3.2 cm. rounded or 3.18309886 cm.
Step-by-step explanation:
<h3>The diameter can be solved using: D =

</h3>
So, the first step would be : D = 
Then : D = 20 ÷ 
Finally, the answer will be : 6.36619772 cm. or 6.4 cm.
<h3>The Radius can be Solved using: r =

</h3>
The first step would be : r = 
Then : 20 ÷ 6.2831853071796 (2
)
Finally, the answer will be : 3.18309886 cm. or 3.2 cm.
Something's not quite right here. What do you mean by "N?"
I could and will make assumptions regarding what you meant. (Feel free to correct me if need be.)
Find the equation of a line through (0,2) <span>which is perpendicular to the line y=3x+3. To find the slope of this perpendicular line, take the negative reciprocal of 3 (the slope of the given line). It is -1/3.
Using the point-slope form of the equation of a straight line:
y = (-1/3)x + 2 (answer)</span>
Answer:-
x=110 degree
Step-by-step explanation:
It's quadrilateral so it's total sum degree is 360
then 40+82+128+x=360
360-(128+82+40)=X
x=360-250
x=110 degree
