Radius of the cylinder is 21 cm.
Step-by-step explanation:
Volume of a solid cylinder
where, r is radius and h is height of the cylinder.
It is given that volume of a solid cylinder is 6237 cm cube and its height is 4.5 cm.
Substitute V=6237, and h=4.5 in the above formula.
Multiply both sides by 7.
Divide both sides by 99.
Taking square root on both sides.
Therefore, the radius of the cylinder is 21 cm.
