Answer 2

Answer:

let radius =2x m

then height=3x m

base area =π radius^2=12.56

=> 3.14.(2x)^2=12.56

=> 4x^2=12.56/3.14=4

=> x^2=4/4=1

=> x=√1

=> x=1

so radius of the cylinder =2 m

height if the cylinder=3m

volume of the cylinder=π radius^2 height

=3.14.(2)^2.3 cu m

=3.14*4*3 cu m

=12*3.14 cu m

=37.68 cu m
