Question

Draw a circle and name its centre a radius a diameter and arc

Answer 1

Answer:

Step-by-step explanation:

Tangents pa and pb are drawn to the ellipse x^2/16 + y^2/9=1 from the point (0,5). Find the area of triangle pab

Answer 2

Given,

The geometrical shape which we need to draw is a circle.

To find,

Drawing the given geometrical shape and marking it's centre, radius , diameter and arc.

Solution,

We can easily draw a circle with the help of the pencil compass which we can get in our geometrical box.

• The point where the stationary point of the pencil compass is situated during the drawing of circle, is known as the centre of the circle. (Marked as O in the attached diagram.)
• The straight line which starts from centre of the circle and ends in any point on the circumference of the circle is known as the radius. (Marked as OA in the attached diagram.)
• If we extend the straight line of the radius to the opposite side's circumference, then the new straight line is known as the diameter of the circle. (Marked as AB in the attached diagram.)
• The curved line between any two points on the circumference of a circle is known as the arc of the circle. (Marked as XY in the attached diagram.)

Hence, the drawing and marking of the given geometrical shape are done.
