Here,
A sphere has 7cm radius
And it’s cut into tow half (2 hemispheres)
So, the radius of a hemisphere is also 7cm
Now,
TSA of hemisphere = 3 pie r^2
=3*22/7*7^2
=3*22/7*49
=3234/7
=462cm^2
Lastly,
The TSA of 2 hemispheres = 2* 462
=924cm^2
Hence,
The total surface area of the 2 hemisphere is 924cm^2
