The slope = (y2-y1) / (x2-x1)
= (7-3) / (2- -2)
= 4/4
= 1
using the point/slope form of a line:-
y - y1 = m(x - x1)
y - 3 = 1(x - -2)
y = x + 2 + 3
y = x + 5 (answer)
Answer:
4π ≈ 12.5663706144
Step-by-step explanation:
The circumference of a circle is 2πr, or 2*pi*radius
Suppose the circle has a diameter of 4 inches. A diameter is 2x the radius, of which we are looking for, therefore:
4÷2=<u>2 inches</u> (radius length)
Now that we have the radius, let us <u>substitute</u> to find the circumference:
2πr=
2π2=
4π≈
<u>12.5663706144</u>
<u></u>
