Cone-shaped 47363

We built a cone-shaped shelter with a base diameter of 4 m on the children's playground. Calculate the cone shell if the side of the cone measures 8 m

Correct answer:

S =  50.2655 m2

Step-by-step explanation:

D=4 m s=8 m  r=D/2=4/2=2 m  s2 = h2+r2  h=s2r2=8222=2 15 m7.746 m  S=π r s=3.1416 2 8=50.2655 m2
