Question

The total surface area of cylindrical tank of radius 7m and
height 3m is
220m
(b) 440m3 (c) 880m2 (d) none of these
​

Answer 1

Total surface area of the cylinder =2π×r(h+r)

Total surface area of the cylinder =2π×r(h+r)=2× 722 ×7×(7+3)=44×10=440m

Total surface area of the cylinder =2π×r(h+r)=2× 722 ×7×(7+3)=44×10=440m Sheet of metal required =440m
