Answer:
Step-by-step explanation:
CSA of cylinder=154msq
2πr2h=154
2×22/7×r2×3.5=154
r2=154×7/2×22×3.5
r2=7×5/5
r= √7m
Volume of cylinder=πr2h
=22/7×√7×√7×3.5
=22×3.5
=77mcube
=77×1000
=77000liter

csa of cylinder =154 msq
2×pie×r×h=154
2×22/7×r×3.5=154
44×.5=154
22=154
154/22=7
volume of cylinder = pie×r2×h
=22/7×49×3.5
=593
593 ×1000
