Answer:
6.5 ft
Step-by-step explanation:
Surface area of the cone = [tex]\pi rl[/tex]
diameter = 6.2 ∴radius = 3.1
63.30 = [tex]\pi (3.1)l[/tex]
[tex]\frac{63.30}{\pi (3.1)} = l[/tex]
l = 6.4996 = 6.5 ft
Answer:
Slant height of cone is:
6.5 ft
Step-by-step explanation:
Surface area of the cone = [tex]\pi rl[/tex]
where r is the radius and l is the slant height
Diameter = 6.2 ft
Radius =Diameter/2
=3.1 ft
⇒ r=3.1 ft
Surface area=63.30 ft²
63.30 = [tex]\pi (3.1)l[/tex]
[tex]\dfrac{63.30}{\pi (3.1)} = l[/tex]
⇒ l = 6.5 ft
Hence, slant height of cone is:
6.5 ft
