Question

how much metal sheet is required to make a closed cylindrical tank of height 50 cm and diameter of base 112 cm find the area of metal sheet in square metre​

Answer 1

3.73 sq. m. of metal sheet is required to make a closed cylindrical tank.

Step-by-step explanation:

Given,

Height = 50 cm

Diameter of base = 112 cm

$radius =\frac{diameter}{2}=\frac{112}{2}=56\ cm$

We have to find out the area of metal sheet required to make the closed cylindrical tank.

Solution,

Since the cylindrical tank is closed, so we will calculate the total surface area of cylindrical tank.

Total Surface Area of Cylindrical tank = $2\pi r(h+r)$

On substituting the values, we get;

Total Surface Area of Cylindrical tank =$2\pi\times56(50+56)=2\times3.14\times56\times106=37278.08\ cm^2$

For converting $cm^2$ to $m^2$, we will divide by 10000.

Total Surface Area of Cylindrical tank =$\frac{37278.08}{10000} =3.727808\approx3.73\ m^2$

Hence 3.73 sq. m. of metal sheet is required to make a closed cylindrical tank.
