A cylindrical container is to be made of tin. The height of the container is 1 m and the diameter of the base is 1 m. If the container is open at the top and tin sheet costs Rs 308 per m22, what will be the cost of tin for making the container?
Answers
do it by using this formula
2πrh+πr²
bcz cruved surface area and a ring surface area will be added to get the answer
Step-by-step explanation:
A cylindrical container is to be made of tin sheets.The height of the container is 1m & diameter is 70cm. If the container is open at the top & tin sheet costs of Rs.30m².
To find:
The cost of tin sheet for making the container.
Solution:
⚫Diameter of the base of container, d=70cm.
=) Radius, r= d/2
=) 70/2
=) 35cm
⚫Height of the container, h= 1m.
We know, 1m= 100cm.
Now,
•Area of tin sheet required:
Curved surface area+area of circle base.
•We know formula of CSA;
=) 2πrh
&
•Area of circular base;
=) πr²
Therefore,
•Convert in m;
1cm²= 1000m²
=) 2.585m²
So,
⚫Cost of 1m² of tin sheet= Rs.30m²
Cost of 2.585m² of tin sheet;
=) Rs.(30 × 2.585)
=) Rs. 775.50
Hence,
The cost of tin sheet for making the container is Rs.775.50.
Hope it helps ☺️
