​

Answer 1

Step-by-step explanation:

triangle = pi*r*l

hemisphere= 2*pi*r*r

Answer 2

Answer:

[(pi×r²)/2 + (base × height)].

Step-by-step explanation:

Surface Area of Circle is pi r².

Therefore, Surface Area of half-Circle is (pi r²)/2.

Surface Area of right-angled triangle is ½×base×height.

Therefore, Surface Area of two right-angled triangles are =base × height .
