Step-by-step explanation:
To find the volume of a pencil, you need to use the formula for the volume of a cylinder, which is:
V = πr²h
where V is the volume, π (pi) is a mathematical constant approximately equal to 3.14, r is the radius of the circular base of the cylinder (in this case, the radius of the pencil), and h is the height of the cylinder (in this case, the length of the pencil).
To find the radius of the pencil, you can measure the distance across the circular cross-section of the pencil at its widest point. Divide this distance by 2 to get the radius.
To find the length of the pencil, you can measure it from one end to the other end.
Once you have the radius and length, you can substitute these values into the formula for the volume of a cylinder and calculate the volume of the pencil in cubic units (e.g. cubic centimeters or cubic inches).
