Answer:
Step-by-step explanation:
Volume of the cylinder= πr²h
Volume is given 1100 sqm
Height = 14m
Putting values in the formulae:
Volume of the cylinder= πr²h
1100 = 22/7 × r² × 14
1100 × 7/22 × 14 = r²
4900 = r²
√4900 = r
r = 70 m
Total surface area of cylinder = 2πrh + 2πr²
= 2× 22/7 × 70 × 14 + 2× 22/7 × 70²
= 6160 + 30800
= 36960 sq.m
