The volume is the length of the pencil multiplied by the cross sectional area.
Cross Sectional Area = pi * radius2
in this case the radius is half the diameter, which is 0.15cm
So, Cross Sectional Area = pi * (0.15 * 0.15) = 0.0707 cm2
So the total volume is 7cm * 0.0707 cm2
which is 0.4948 cm3

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

Calculate the diameter of a cylinder whose height is the same as its diameter and whose volume is 220cm?
Volume = Height * Area of Circle Area of Circle = pi*(Diameter/2)^2 Height = Diameter Volume = Diameter*(pi*(Diameter/2)^2) Volume = (pi/4)*Diameter^3 Diameter = (4/pi) * Volume ^ (1/3) Diameter = (4/3.14)*220^(1/3) ≈ 6.54 cm

How do you find the cubic feet of dryer?
For the exterior you measure the lenght, width and height - in feet - and multiply them together. To measure the interior volume you will need to measure the diameter of the drum and its depth, in feet. Then volume = 1/4*pi*diameter2*depth.

How many cubic inches in a tank with a diameter of one foot and a lenght of 19 inches?
Volume = pi*r2*h, where h is the height (or length). Diameter = 1 foot so radius, r = 6 inches. So vol = 2148.8 cubic inches or 1.24 cu ft
