Question

5. Draw a circle with any radius. Shade the circular region​

Answer 1

To Find: A circle of any radius and shade the circular region.

Explanation:

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, it has rotational symmetry around the center for every angle.

The circle formula in the plane is given as: (x-h)² + (y-k)² = r², where (x, y) are the coordinate points (h, k) is the coordinate of the center of a circle and r is the radius of a circle.

How to draw a circle:

Step 1: Place the pointer of the compass at the initial point of the ruler (0 cm) and extend the other end of the pencil measuring 5 cm from the initial point. (Let the radius be 5 cm.)

Step 2: Mark a point O on a piece of paper. This point is supposed to be the center of the circle that you are about to construct.

Step 3: Place the pointer of the compass at point O.

Step 4: Turn the compass slowly through 360 degrees to draw a circle.

The circular region is given below:
