Question

A solid cylinder and a solid cone of equal base and equal heights,
have the ratio of radius to height as 4:3. Find the ratio of the
total surface area of cylinder to that of cone. 1414​

Answer 1

Answer:

2:3

Step-by-step explanation:

surface area of the solid cylinder =2 pi r h

surface area of the solid cone=pi r ( l+ r)

radius : height=4:3

radius =4x & height =3x

hence,2 pi 4x 3x :pi 4x (5x+4x).....(l= 5 because r^2+h^2=l^2)

2 pi 12 x^2:pi 36x^2

= 2:3
