Question

Three iron cylinders of Radi 5 cm ,6cm and 30 cm of equal height are method and into a cylinder of same height find radius

Answer 1

Answer:

31cm

Step-by-step explanation:

volume of cylinder = pi r^2 h

so combined volume of the three cylinders =pi h (25+36+900)

=pi h(961)

volume of combined cylinders = the volume of the new cylinder formed

pi h r^2=pi h 961

r^2=961

r=31 cm
