Answer:
2.512
Step-by-step explanation:
the equation for circumference of a circle is
2(pi)r
plug in the 4
2(pi)4
combine like terms
8(pi)
you can leave the answer as is or you can multiply
8(3.14)= 2.512
the answer would be 2.512
***pi is equal to 3.14, if you are not allowed to keep your answer in terms of pi there is a pi button on the calculator you can use, or simply plug in 3.14

1.
Any 3 lines a, b and c intersect and form triangles, in no 2 of them are parallel.
2.
2 lines are parallel only if their slopes are equal.
3.
if the equation of a line l is given in the form y=
mx+t, then m, the coefficient of x, is the slope of that line.
4.
so given lines a, b, c with equations:
if
, then the lines intersect, forming thus a triangle.
5.
let the 3 lines be:
Answer:
30°
Step-by-step explanation:
It's an equilateral triangle, which means that the angle at the center is 60°. The angle where the tangent line touches the circle is 90°. You have 2 out of 3 angles. Now all you have to do is subtract the two angles from 180°.
180 - 90 - 60 = 30
