Answer:
21 cm
Step-by-step explanation:
Volume of cone is given by
volume of cylinder is given by
where r is the radius of base and h is the height
_________________________________
For cone
radius = 42cm
height = 84
volume = (1)
________________________________
For cone
radius = to find let it be r
height =112
volume = (2)
_______________________________________
since , volume of both solid are same
thus, equation 1 = equation 2
Thus, radius of cylinder is 21 cm
