The Indian tent

The Indian tent is cone-shaped. Its height is 3.5 m. The diameter of the base is 2.5 m. How much canvas is needed to make a tire?

Correct answer:

S =  14.5947 m2

Step-by-step explanation:

h=3.5 m D=2.5 m  r=D/2=2.5/2=54=1.25 m s=h2+r2=3.52+1.2523.7165 m  S=π r s=3.1416 1.25 3.7165=14.5947 m2
