Question

if two solid hemisphere of same base radius 14 cm are joined together along their bases then find the surface area of the new solid obtained​

Answer 1

Answer is 69cm okkkkkk

Answer 2

The surface area of the newly obtained solid is 2464 cm².

Given data :

The base radius of the two hemispheres is 14 centimetres.

• Now,if two solid hemispheres of same radius are attached with each other along their base then a solid sphere will be created.

• So,we have to calculate the surface area of a sphere of the same radius given for the two hemispheres.

• Radius of the formed sphere = 14 cm

• Curved surface area of the sphere = 4 × π × (radius)²

= 4 × 22/7 × (14)²

= 4 × 22/7 × 196

= 4 × 22 × 28

= 2464 cm²

So,the surface area of the newly formed solid is 2464 cm². (Answer)
