Question

total surface area of hemisphere​

Answer 1

Step-by-step explanation:

Total surface area of sphere is 4πr²

So total surface area of hemisphere will be 4πr²/2=2πr²

but but but.....

downward one circle is left so.

Surface area of that circle is πr²

Total surface area of hemisphere =2πr²+πr²

=3πr²

Mark as brainliest answer.

Follow me I will follow you back.

Answer 2

Answer:

Step-by-step explanation:

Total surface area of a hemisphere is half of that of a sphere i.e 4pie r^2/2

i.e 2pie r^2

But we have only obtained its curved surface area

Therefore total surface area=C.S.A of hemisphere + Area of its base circle

=2pie r^2+pie r^2

=3pie r^2
