How could you use a piece of string thumbtack and a pencil to construct a circle with radius AB?
Loop the string around the thumbtack and the pencil so that the distance from the tack to the pencil point is AB units. Fix the thumbtack to where you want the centre of the circle. Using the pencil, and with the string taut, mark its positions. These will lie on a circle with radius AB.

How do you construct a circle that has radius with an equal length to the given line segment?
Adjust the compass to the given line segment then construct the circle.
What is needed to construct a hexagon?
To construct a hexagon, you need a compass, a straightedge (ruler), and a pencil. Start by drawing a circle with the compass; the radius will determine the size of the hexagon. Then, using the same radius, mark off six equal points around the circle's circumference, which will serve as the vertices of the hexagon. Finally, connect these points with straight lines to complete the hexagon.
How can you use a compass to draw a circle if you know its raduis or diameter?
If you know the radius place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle. If you know the diameter divide by two to get the radius and place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle.
How do draw a circle with a compass?
To draw a circle with a compass, first set the distance between the point and the pencil of the compass using a ruler. This distance is the radius. Now, place the point on the paper where you want the center of the circle. Spin the compass around the point, lightly dragging the pencil on the paper, and you will have a circle.
How do you construct the triangle if its sides are not given and the measures of angles are 50 60 and 70 the radius of the circumcircle is 32?
1) Draw a circle of radius 32 2) Draw a radius (meeting the perimeter at A) 3) Based on the radius, construct an angle at the centre of the circle of 100° - draw a second radius (meeting the perimeter at B) 4) Based on the second radius, construct an angle at the centre of the circle of 120° - draw a third radius (meeting the perimeter at C) Note : the angle between the third and first radii measures 140°. 5) Draw chords joining A to B, B to C, and C to A. The triangle ABC has angles measuring 50°, 60° and 70°. NOTE : The process is based on the Theorem that the angle subtended by an arc at the centre of a circle is twice the angle subtended at any point on the circumference.

You exert a force of 23 N on the head of a thumbtack The head of the thumbtack has a radius of 4 mm What is the pressure on your thumb?
Pressure equals force/area. Force equals 23 Newtons (N) and area of a circle equals 3.14*radius^2. Therefore pressure equals .46N per mm. l
You exert a force of 25N on the head of a thumbtack the head of the thumbtack has a radius of 5mm what is the pressure on your thumb?
The pressure on your thumb can be calculated by dividing the force (25N) by the area of the thumbtack head in contact with your thumb. The area can be found using the formula for the area of a circle, A = πr^2, where r is the radius (5mm). Therefore, the pressure on your thumb is 25N / (π * (5mm)^2) = 1N/mm^2, or 1 MPa.
How many radius in a circle?
It depends on how sharp your pencil is! (A boring person would say "infinity")

How do you draw the circle with radius 30cm?
-- Stick a nail into a board. -- Tie a piece of thread around a pencil. -- 30 cm from the pencil, stick the thread to the nail. -- Draw a line on the board with the pencil. Keep the thread tight and go all the way around the nail. -- The line is a circle with radius 30 cm.

How do you divide a circle with 9cm diameter in three equal parts?
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
