You can use the circumference of the pencil and the circumference formula to find the radius. Set the measured circumference equal to 2pi*radius and solve.
I measured it to about .75 of an inch, so:
.75=2pi*radius
r=.75/2pi

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 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.
What steps do you use to find the volume of a pencil?
For finding accurate volume of a pencil use a vernier calliper, which measures diameter up to two significant figures. For finding volume of a pencil you will need radius (r) and length (L) of the pencil. V = 3.14 r²L
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 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 many radius in a circle?
It depends on how sharp your pencil is! (A boring person would say "infinity")

How do you make a compass with a magnetized nail and stringand plastic jar with lid and tape?
The idea is to draw a circle (two actually), using the ends of the paperclip to establish the radius of the circle, one pencil to anchor an end of the paperclip as the center of the circle, and a second pencil at the opposite end of the paperclip to draw the circle. Step by step, with the following diagram of characters, where the 'x' shows the place of the pencil that does not move, as the center of the circle, 'y' shows the place of the second pencil that moves to draw the small circle, and 'z' shows the place of the second pencil that moves to large small circle: (x______y)__z) # Place the paperclip on a piece of paper; # Put the first pencil inside the end of the paperclip that has just one loop ('x' above in the diagram). This pencil stays put, and is the center of the circle; # Put the second pencil inside either of the loops at the other end of the paperclip. Move this second pencil to draw a circle.
