The volume of a cylinder is 252π cm3 and its height is 7. what is the cylinders radius? a. 36 b. 80 c. 16 d. 6

The volume of a cylinder is given by the formula;
Volume = πr²h, where r is the radius, and h is the height or the length 
Therefore,
252 π cm³ = π r² (7)
           r² = 252/7
              = 36
            r = √36
               = 6 cm .
Hence, the radius of the cylinder is 6 cm
           

The answer would be d i think but i’m for sure it is not a and c
