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")

What is the area of a pencil case?
The area of a pencil case depends on its shape. If it is a rectangular prism, you would calculate the area by multiplying the length by the width. If it is a cylindrical pencil case, you would use the formula for the surface area of a cylinder, which is 2πrh + 2πr^2, where r is the radius and h is the height.

What bones are important for holding a pen or pencil?
The bones in the hand and forearm – including the radius, ulna, carpals, metacarpals, and phalanges – work together to support the hand and fingers in holding a pen or pencil. The thumb's opposition to the other digits is crucial for a precision grip when writing.
