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

Respuesta :

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
