Observatory

The observatory dome has the shape of a hemisphere with a diameter d = 10 m. Calculate the surface.

Correct answer:

S =  157.0796 m2

Step-by-step explanation:

D=10 m  S=π2 D2=3.14162 102=157.0796 m2D = 10 \ \text{m} \ \\ \ \\ S = \dfrac{ \pi }{ 2 } \cdot \ D^2 = \dfrac{ 3.1416 }{ 2 } \cdot \ 10^2 = 157.0796 \ \text{m}^2
