Step-by-step explanation:
When a slope of a line and a point passing through it is given then we use slope - one point form to determine the equation of the line.
It is given by:
where 
is the slope of the line and
is the point passing through it.
Here, 
and 
.
Substituting in the formula 
Answer:
Step-by-step explanation:
diameter = 4.275"
r = 4.275 ÷ 2 = 2.1375"
Area of circle = πr²
= 3.14 * 2.1375 * 2.1375
= 14.3463
≈ 14.3 in²
