Answer:
Step-by-step explanation:
Given the equation
comparing the equation with the slope-intercept form
Here,
- m is the slope
- y is the intercept
so the slope of the line is 2/7
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
the slope of the perpendicular line will be: -7/2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (4,-6) is:
Circumfrence: pi times diameter

circumfrence is approximatley 24.806
area:
a=*(1/2(d))^2
a= 48.99
