The circle shown above has a radius of 4. The central angle, a, of the sector is 2/3n and the arc length represented by b
1 answer:
A circle is a curve sketched out by a point moving in a plane. Except for the first statement both the second and the third statement is true.
<h3>What is a circle?</h3>A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.
The complete question is mentioned in the below image.
For the given circle,
The area of the sector is,
Area of sector = π(4)²×[2π/(3×2π)] = 16π/3
The area of the circle is,
Area of the circle = π×(4)² = 16π
The length of the Arc is,
Length of the arc = 2π×(4)×[2π/(3×2π)] = 8π/3
Hence, Except for the first statement both the second and the third statement is true.

B.
Step-by-step explanation:
Given:
(2, 4) and (2, -9)
Required:
Midpoint of the vertical line with the above endpoints
Solution:
Apply the midpoint formula, which is:
Where,
(2, 4) = (x_1, y_1)
(2, -9) = (x_2, y_2)
Plug in the values into the equation:
