This is the concept of algebra, we are required to calculate the area cut out of a cylinder represented by the function x^2+z^2=36;
The equation of a circle is given by:
(x-a)^2+(y-b)^2=r^2
where;
(a,b) are the center of the circle;
r=radius of the circle
re-writing our equation we have:
x^2+z^2=36
(x-0)^2+(z-0)^2=6^2
this implies that the center of the circle is (0,0) and the radius is 6 units;
Therefore the area will be given by:
Area=πr^2
Area=π*6^2
Area=36π=113.1 sq. units
Answer:
The expression for two times the difference of eight and d. is
Step-by-step explanation:
To Find:
Write an expression for two times the difference of eight and d.
Solution:
Difference of 8 and d = ( 8 - d )
So One Time Difference of 8 and d = 1× ( 8 - d )
∴ Two Times Difference of 8 and d = 2× ( 8 - d )
The expression for two times the difference of eight and d. is
Answer:
3
Step-by-step explanation:
-(x-4)+5=3x+6-x(BODMAS)
-x+4+5=3x+6-x(collect like terms )
4+5=3x+x-x
9=3x (divide both sides by 3)
9/3=3x/3
3=x
