the radius and height of a right circular cylinder are in the ratio of

1.	the radius and height of a right circular cylinder are in the ratio of 2:3 if the volume of the cylinder is 1617 cm².then find the radius and height of cylinder
Answer» ANSWER: Let the RADIUS of the base of the cylinder be 2x and its height be 3X. Volume of a cylinder = (2x)2 (3x) = 1617 X = = 3.5 CM r = 7 cm, h = 10.5 cm Curved surface area of the cylinder = 2rh

Answer»

Let the RADIUS of the base of the cylinder be 2x and its height be 3X.

Volume of a cylinder =

(2x)2 (3x) = 1617

X = = 3.5 CM

r = 7 cm, h = 10.5 cm

Curved surface area of the cylinder = 2rh
