Answer:
Volume of 1st cylinder =πr²h
π=3.14,r=?,h=1
=3.14×r²×1
=3.14×r²
r²=3.14
r=√3.14=1.77
The radius of the first cylinder is 1.77
Volume of 2nd cylinder =πr²h
π=3.14,r²=?,h=4
=3.14×r²×4
=12.56×r²
r²=12.56
r=√12.56=3.54
The radius of the second cylinder is 3.54
The ratio of radii of the cylinder are 1.77:3.54
