A = pi (r)^2
so with 222r
circle changes by a factor of 222^2
Step-by-step explanation:
Hey there!
Follow the steps to get answer.
- Use one point formula and find 1st equation.
- After that you find the slope of second equation.
- Use the condition of perpendicular lines and find the slope of first equation.
- Put slope value of equation in equation (i) and simplify them to get equation.
The equation of a line passing through point (2,3) is;
(y-3)= m1(x-2).......(i).
Another equation is;

2nd equation..
Now, From equation (ii)
We have;
Comparing equation (ii) with y = mx+c.
We get;
Slope = -1/2.
For perpendicular lines,


Therefore the slope is 2.
Put value of slope (m1) in equation (i). We get;

Simplify them to get equation.


Therefore the required equation is y = 2x-1.
