The roof has a spherical canopy with a base diameter of 8 m and a height of 2 m. Calculate the foil area with which the roof is covered when calculating 13% for waste and residues.

Correct answer:

S =  56.8 m2

Step-by-step explanation:

d=8 m v=2 m  ρ=d/2=8/2=4 m  S1=2π ρ v=2 3.1416 4 250.2655 m2  q=13%=1+10013=1.13  S=q S1=1.13 50.2655=56.8 m2
