An Ironbar 2m Long And 0.4m In Diameter

An ironbar 2m long and 0.4m in diameter

Answer:

If you are asking about volume, the answer is 0.251 $m^3$

If you are asking about total surface area, the answer is 2.765 $m^2$

Step-by-step explanation:

An ironbar is a cylinder and a cylinder is a solid bounded by a closed cylindrical surface and two parallel planes.

To calculate the volume of the cylinder, the following formula will be used

$V = (\frac{\pi d^2}{4})h$

Using the given height and diameter we have

$V = (\frac{\pi (0.4m)^2}{4})(2m)\\V = 0.2513 m^3$

To calculate the total surface area TSA of the cylinder, the following formula will be used

$TSA = \frac{\pi d^2}{2} + \pi dh\\TSA = \frac{\pi (0.4m)^2}{2} + \pi (0.4m)(2m)\\TSA = 2.765 m^2$
