Question

If the diameter of a hemisphere is 8 cm, then its curved surface area would be​

Answer 1

Curved surface area of a hemisphere = 2π r^2

r = 8 cm

CSA = 2π (8*8)

= 2π (64)

= 128 π cm square

Answer 2

Answer:

100.57 cm²

Step-by-step explanation:

curved surface area = 2$\pi$r²

                                  = 2$\pi$ (4)²

                                  = 100.57 cm²
