The ratio between the radius of the base and the height of a cylinder

1.	The ratio between the radius of the base and the height of a cylinder is 2:3. If its 1617cm3then its total surface area is (a) 308 cm2 (b) 462 cm2 (c) 540 cm2 (d) 770 cm2
Answer» The ratio between the radius of the base and the height of a cylinder is 2:3. If its 1617 $c m^{3}$ then its total surface area is $(a) 308 c m^{2} (b) 462 c m^{2} (c) 540 c m^{2} (d) 770 c m^{2}$

Answer»

The ratio between the radius of the base and the height of a cylinder is 2:3. If its 1617 $c m^{3}$ then its total surface area is

$(a) 308 c m^{2} (b) 462 c m^{2} (c) 540 c m^{2} (d) 770 c m^{2}$
