lateral area of cylinder = circumference * height\[A _{l}=2\times \pi \times r \times h\ ...........(1)\] area of base is given by\[A _{b}=\pi \times r ^{2}\ ...........(2)\] \[A _{l}+A _{b}=3000=(2\times \pi \times r \times 50)+(\pi \times r ^{2})\ ........(3)\] You can form a quadratic equation from (3) and one of the solutions is the radius.

The quadratic equation is as follows: \[\pi r ^{2}+100\pi r3000=0\] You need to solve this to find r the radius of the vase.
