Answer:2.25cm
Step-by-step explanation: To find the radius of the length, then we are going to have,
Volume of a cylinder=πr^2h
Radius =? H=15cm V=240n cube cm
240ncm^3=3.142×r^2cm×15cm
240cm^3=47.13r^2
The next thing is to divide through by 47.14
r^2=5.09229
Take the square root of both sides, then our answer will be given as;
r=2.25cm
