Question

A solid metallic sphere of radius 14 cm is cut into 2 halves . Find the total surface area of 2 hemisphere so formed​

Answer 1

Answer:

hopefully this will help u

Answer 2

${ \huge{ \underline{ \underline{ \sf{ \green{GivEn : }}}}}}$

• Radius of sphere is = 14cm

${ \huge{ \underline{ \underline{ \sf{ \green{To \: find :}}}}}}$

• Total surface area of 2 hemisphere

Formula to be used :-

• Total surface area of Hemisphere = 3πr

${ \huge{ \underline{ \underline{ \sf{ \green{SoluTion : }}}}}}$

Given that,

Radius of sphere is = 14cm

Where,

Radius of sphere = Radius of Hemisphere

= 14cm

Now, find the Total surface area of Hemisphere

Total surface area of Hemisphere

= 3πr²

= 3 × 3.1416 × ( 14)²

= 1848 cm²

Hence,

Total surface area of each hemisphere is

1848cm²
