Answer 1

Answer:

answer for the given problem is given

Answer 2

Answer:

First the radius of the balloon = 6 cm

First the radius of the balloon = 6 cmSecond the radius of the balloon = 12 cm.

First the radius of the balloon = 6 cmSecond the radius of the balloon = 12 cm.Now,

First the radius of the balloon = 6 cmSecond the radius of the balloon = 12 cm.Now,Surface Area of a hemisphere

First the radius of the balloon = 6 cmSecond the radius of the balloon = 12 cm.Now,Surface Area of a hemisphere= 3*pi*radius ^2

First the radius of the balloon = 6 cmSecond the radius of the balloon = 12 cm.Now,Surface Area of a hemisphere= 3*pi*radius ^2So

First the radius of the balloon = 6 cmSecond the radius of the balloon = 12 cm.Now,Surface Area of a hemisphere= 3*pi*radius ^2SoThe ratio of the surface areas will be

First the radius of the balloon = 6 cmSecond the radius of the balloon = 12 cm.Now,Surface Area of a hemisphere= 3*pi*radius ^2SoThe ratio of the surface areas will be= 3*pi*(6)^2 : 3*pi*(12)^2

First the radius of the balloon = 6 cmSecond the radius of the balloon = 12 cm.Now,Surface Area of a hemisphere= 3*pi*radius ^2SoThe ratio of the surface areas will be= 3*pi*(6)^2 : 3*pi*(12)^2= 6^2 : 12^

First the radius of the balloon = 6 cmSecond the radius of the balloon = 12 cm.Now,Surface Area of a hemisphere= 3*pi*radius ^2SoThe ratio of the surface areas will be= 3*pi*(6)^2 : 3*pi*(12)^2= 6^2 : 12^= 36 : 144

First the radius of the balloon = 6 cmSecond the radius of the balloon = 12 cm.Now,Surface Area of a hemisphere= 3*pi*radius ^2SoThe ratio of the surface areas will be= 3*pi*(6)^2 : 3*pi*(12)^2= 6^2 : 12^= 36 : 144= 1 :4

First the radius of the balloon = 6 cmSecond the radius of the balloon = 12 cm.Now,Surface Area of a hemisphere= 3*pi*radius ^2SoThe ratio of the surface areas will be= 3*pi*(6)^2 : 3*pi*(12)^2= 6^2 : 12^= 36 : 144= 1 :4# follow me
