Answer:
3
Step-by-step explanation:
The answer:
the calculus of the circumference depends on what is the value of central angle, so we can take for example 120° the value of the central angle.
<span>since the length of arc ab is 28.61, and the central angle is 120°, we can find the circumference simply by using the following formula:
ARC = Radius x Angle, so Radius = ARC / Angle = 28 .61 / 120° = 0.23 unit
the circumference of a circle is C = 2 x radius x Pie
</span>C = 2 x radius x Pie = 2 x 0.23 x 3.14 = 1.49 unit
Answer:
(3, -2)
Step-by-step explanation:
The <em>midpoint</em> of two points is half-way between the x-values and the y-values.
The formula is
M = ((x₁ + x₂)/2, (y₁ + y₂)/2)
For the points (5,-5) and (1,1),
Half way between the x values is
(x₁ + x₂)/2 = (5 + 1) /2 = 6/2 = 3
Half way between the y values is
(y₁ + y₂)/2= (-5 + 1)/2 = -4/2 = -2
M = (3, -2)
The graph below shows your two points at (5,-5) and (1,1) and the mid-point at (3, -2).
4 is 18 because 6x3 is 18
