corrected by

Answers to the exercises on the circle in 6th grade with problems on the construction of circles and the drawing of chords in 6th grade.

Exercise 1:

1. Draw a circle with center O and a string [AB] as below.

2. Draw a string [BC] so that the point O is inside the triangle ABC.

3. Draw a string [BE] so that the point O is outside the triangle ABE.

Exercise 2:

1.2. Here is the figure we get:

3. Indicate for each point A,E,F,G,H whether or not it belongs to the circle $\varphi$ .

Only the point G belongs to the circle because AG=2 cm = radius

Exercise 3:

1. Draw a segment [EF], then the circle with center E passing through F.

2. Draw the circle with center F and radius EF.

Exercise 4:

1. Draw a segment [PQ] and place its middle H.

2. Draw the circle with center H passing through P.

Name a segment that is a diameter of this circle.

The segment [PQ] is a diameter of this circle.

Exercise 5:

1. Place on the sheet two points A and B distant of 4 cm.

2. Draw the circle with center A passing through B.

What is its radius? its diameter?

Its radius is 4 cm and its diameter is 8 cm.

Exercise 6:

1. Place a point O on the sheet.

Draw the circle with center O and radius 3 cm.

2. Draw the circle with center O and diameter 5 cm.

Exercise 7:

Exercise 8:

b) This figure corresponds to 2 small circles of radius 3 cm and one large circle of radius 6 cm .

$P=2\times \,2\times \,\pi\times \,3+2\times \,\pi\times \,6$

$P=12\pi+12\,\pi$

$P=24\pi$

$P\simeq\,75,4\,cm$
