Here's ur answer...
given radius is 7m and height is 21m
TSA of the cylinder=2πr(h+r)
=2×22/7×7(21+7)
=44×28
=1232m²
hope this helps...

Answer:
Radius =7cm.
Height =39cm.
Volume = πr^2 h
= 7/22 × 7×7×30
= 154×30
= 4620cm^3.
Now, Total surface area of the cylinder =2πr(r+h)
= 2 × 7/22 × 7×(7+10) = 44×17
= 748cm^2 .
