Answer»

Answer:

12CM

Step-by-step explanation:

the RATIO of HEIGHT and radius of a corn = 7:4

And, it's curved surface area = 792 cm2

let the height and radius of the corn be 7X and 4x

πrh = 792cm2

22/7*7x*4x = 792cm2

88x2 = 792cm2

x = √792cm2/88

x = √9cm2

x = 3cm

radius of a corn = 4x

= 4*3cm

= 12cm
