Answer:
For the first one just multiply all of the three numbers
and the second is the same, just multiply and you'll get your answer.
Step-by-step explanation:
The line
is already written in the
form. This means that
is the slope. If two lines are perpendicular, their slopes are the anti-inverse of each other, i.e. their product is -1.
So, our perpendicular line has a slope of 
Finally, we want a line passing through (1,1) with slope
:

Step-by-step explanation:
the answer is in picture
The area of a circle is given by the formula:
A =

r^2
Since

= 3.14, and r = 6, sub these values into the equation,
A = 3.14 x 6^2
= 113.04
Hope this helped!
