Answer:

A closed metallic cylindrical box is 15 m high and it has a base whose radius is 21 cm. If the sheet of metal costs Rs. 70 per sq. m, find the cost of the material used in the box.

h=15 m  

r=21cm

TSA  =2πrh+2πr^2

=2πr(r+h)

=2×22​×21(15)

      7

=42x 22/7+15   146.999...

=147

Cost =70×147(cost by us)

=10,290Rs.
