Castle tower

The castle tower has a cone-shaped roof with a diameter of 10 meters and a height of 8 meters. Calculate how much m² of coverage is needed to cover it if we must add one-third for the overlap.

Correct result:

S =  197.5848 m2


D=10 m h=8 m  r=D/2=10/2=5 m  s=h2+r2=82+52=89 m9.434 m  S1=π r s=3.1416 5 9.434148.1886 m2  S=(1+13) S1=(1+13) 148.1886=197.5848 m2
