Question

Draw a circle of radius 3.2cm.

Answer 1

Hint: We are asked to draw a circle with a radius given. For that we need to be aware about what a circle is. Moreover, we need to be aware about how to use a compass. We will put the pointed end of the compass at the centre and then we stretch the other side of the compass by a length of 3.2cm. After that we simply rotate the compass to form a complete circle.

Complete step-by-step answer:
 A circle is the locus of all points equidistant from a central point. A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. The distance between any point of the circle and the centre is called the radius. We take the compass and put the pointed sharp arm on a piece of paper to point its centre. After that we put the compass on the scale and stretch the arm of the circle to a length of 3.2cm. Then, we put it on the paper we have put our centre at and we rotate it to draw the circle.

Note: We need to be aware about various tools of the geometry box such as the protractor or the compass. We need to be very careful while stretching the other arm of the compass because if it is stretched to a wrong length then the circle of a wrong radius would be formed which would be wrong.
