Question

Draw a circle of radius 1.6cm and draw
(i) a diameter
(ii) a segment
(iii) an arc
(iv) a sector
Name all of them.

Answer 1

Hint: For solving this question you should know about the circle and the different parameters of this. As we know that a circle is a round plane figure whose boundary consists of points equidistant from a fixed point. And the point is always at a fixed half of the diameter of this circle which makes the radius.

Complete step-by-step solution:
According to the question we have to draw a circle of radius 1.6cm and also draw some other elements.
So, as we know that the circle is made through a point, when we draw a line around this point in a way that every point on this line are equidistant from this point and the line have infinite end (no end).
And the diameter is the double of the radius.
So, if we see in the diagram.

Here, AB & BC is the radius and AC is the diameter.
And if we see the sector in a circle, then

And the segment is

And is we see all elements in one diagram, then:

And if we make the circle of 1.6cm radius, then

So, all the elements have been drawn.

Note: For making any diagram of a circle always we have to determine the radius. And the radius can be determined by any area or the peripheral of the circle. And by the formulas the radius can be determined easily and accurate.
