## How do you draw a sector of a circle in Matlab?

Let r be the circle’s radius, P0 = [x0,y0] be its center, and theta be the required angle in radians.

**How do you draw an arc in Matlab?**

How to draw a arc with arc length and angle

- clc;clear all;close all;
- r = 125; % set the rad of arc is 125m.
- l = 180; % set the length of arc is 180m.
- n = ((l*180)/r)/pi; % Get the angal of arc degree.
- N = [0:0.1:n] % N for angal on arc.
- L = (N*pi*r)/180; % L for length for each angal on arc.
- R = [0:0.151:125];

### How do you plot a half circle in Matlab?

how can I draw half circle in matlab ?

- xCenter_2 = 3/(2*sqrt(13));
- yCenter_2 = -1/sqrt(13);
- theta = 0-2/3 : 0.01 : pi-2/3;
- radius = 0.5;
- x = radius * cos(theta) + xCenter_2;
- y = radius * sin(theta) + yCenter_2;
- plot(x, y), hold on;
- axis square;

**How do you plot a circle?**

Center away from the origin

- Locate the center of the circle from the equation (h, v). Place the center of the circle at (3, –1).
- Calculate the radius by solving for r.
- Plot the radius points on the coordinate plane.
- Connect the dots to the graph of the circle with a round, smooth curve.

#### How do you find the arc between two points?

To create an arc by two end points and another point on the arc:

- Click the Arc tool from the Basic palette, and select the Point on Arc mode.
- Click to set the start point of the arc.
- Click to set the end point of the arc.
- Move the cursor until the desired arc shape and size is previewed, and then click to set the arc.

**How do you plot a half circle?**

- The graph of a semi-circle is just half of a circle.
- The equation of the unit circle (radius 1 and centered at the origin) is x^2 + y^2 = 1.
- This can be rewritten y^2 = 1 – x^2 or y = +/- squareroot(1 – x^2).
- If you just want the top half of the unit circle, you can use y = radical(1 – x^2).

## What is the equation of a half circle?

In general, if a circle has center (a,b) and radius r, then its equation is (x−a)2+(y−b)2=r2. The equation for that semicircle is therefore x2+(y−1.5)2=4, with the restriction x≥0.

**What are the 8 parts of a circle?**

In these lessons, we will learn the following parts of a circle: diameter, chord, radius, arc and tangent.

### How do we name a circle?

A circle is named by its center. Thus, the circle to the right is called circle A since its center is at point A. Some real world examples of a circle are a wheel, a dinner plate and (the surface of) a coin. The distance across a circle through the center is called the diameter.
