Surface are of a cylinder: 2(pi)r2 + 2(pi)rh
Volume of a cylinder: 2(pi)r2h
[pi = 3.14159..., r = radius of the cylinder's cross section, h = height of the cylinder]
Pi times radius squared: Pi x r2 for area
pie r
area of the cylinder base multiplied the height of the cylinder
The circumference of a regular cylinder is the circumference of its circular face. C = pi * D (diameter of the cylinder) C = pi * 2r (or C = 2(pi)r)
Neither the area or the volume of the cylinder can be calculated without the length.
the circumfrance of the base x the height of the cylinder
The volume of a cylinder is its height times the area of its base. And the area of its base is the area of a circular shape.
first you get the radius of the base. than you do " pi times radius squared
v=pi.r^2h
that formula is base times height
The formula is (area of the base)*height = (pi)* r2h
(area of base) x (height), so in the case of a cylinder, the base is a circle, so area of base = pi * r2 Volume = pi * r2 * h
v=bh
Volume = {pi}r2h where r = radius of base, h = height of cylinder.
