A cylinder’s volume is π r2 h, and its surface area is
2π r h + 2π r2
. Learn how to use these formulas to solve an example problem.
What is the surface area of the cylinder?
The formula to calculate the total surface area of a cylinder is given as, the total surface area of cylinder
= 2πr(h + r)
, while the curved surface area of cylinder formula is, curved/lateral surface area of cylinder = 2πrh, where ‘r’ is the radius of the base and ‘h’ is the height of the cylinder.
What is surface area and volume?
The
surface area of any given object is the area or region occupied by the surface of the object
. Whereas volume is the amount of space available in an object. In geometry, there are different shapes and sizes such as sphere, cube, cuboid, cone, cylinder, etc.
How do you calculate surface area and volume?
It gives the proportion of surface area per unit volume of the object (e.g., sphere, cylinder, etc.). Therefore, the formula to calculate surface area to volume ratio is:
SA/VOL = surface area (x
2
) / volume (x
3
) SA/VOL = x
– 1
, where x is the unit of measurement.
What is a formula of cylinder?
Solution. The formula for the volume of a cylinder is
V=Bh
or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h .
What is the formula of surface area?
| Surface Area Formula Surface Area Meaning | SA=2B+Ph Find the area of each face. Add up all areas. | SA=B+12sP Find the area of each face. Add up all areas. | SA=2B+2πrh Find the area of the base, times 2, then add the areas to the areas of the rectangle, which is the circumference times the height. |

Is there a relationship between surface area and volume?
The surface area to volume ratio of an object is the relationship between two measurements. This gives them a large ratio of surface to volume. … Larger objects have small surface area compared to the volume so they have a small surface area to volume ratio.
What is difference between area and volume?
An area is a two-dimensional object whereas
volume is a three-dimensional object
. The area is a plain figure while volume is a solid figure. The area covers the outer space and volume covers the inner capacity. The area is measured in square units and volume is measured in cubic units.
How do you find the surface area and volume of a cube?
So for a cube, the formulas for volume and surface area are
V=s3 V = s 3 and S=6s2 S = 6 s 2
.
What is the formula of volume?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is
length × width × height
.
How do you find the surface area and volume of a rectangle?
- Volume of Rectangular Prism: V = lwh.
- Surface Area of Rectangular Prism: S = 2(lw + lh + wh)
- Space Diagonal of Rectangular Prism: (similar to the distance between 2 points) d = √(l

How do you find area?
To find the area of a rectangle or a square you need
to multiply the length and the width of a rectangle or a square
. Area, A, is x times y.
How do you solve surface area and volume problems easily?
- Volume = ( r
2
h) cubic units. - Curved surface area = (2 rh) sq. units.
- Total surface area = 2 r(h + r) sq. units.
What is a total surface area?
The total surface area of a solid is
the sum of the areas of all of the faces or surfaces that enclose the solid
. The sum of the areas of the rectangle and the two circles is the total surface area. … This process can be imagined with each of the solids to picture the lateral surface and the base(s).
