▪Given that ,
=============
⭐Area of Base of Cylinder => 154 cm²
This implies that ,
πr² = 154
22/7 × r² = 154
r² = 154 × 7 / 22
r² => 49
➡Radius => 7 cm
================
⭐Volume of Cylinder => πr²h
= 22/7 × 7 × 7 × 5
=770 cm³
----------------------------------------------------
➡Simple method =>
Area of Base => πr² = 154
▪Volume of Cylinder => πr²×h
=> 154 × 5
=> 770 cm³
