Question

the radii of two cylinders are in the ratio 2:3 and their height are in the ratio 5:3 calculate the ratio of their curved surface area​

Answer 1

Answer is in the picture.

Hope it helps.

Answer 2

Step-by-step explanation:

radio of radii = 2:3

there fore ,

radius are 2x , 3x

ratio of heights = 5:3

there fore ,

heights are 5x and 3x

curved surface area of 1st cylinder = 2π*2x*5x =20xsq.π

curved surface area of 2nd cylinder = 2π * 3x * 3x =18πx sq.

there fore ,

ratio of curved surface area = 20πx sq. : 18 π x sq.

= 5:3
