Answer:
Therefore Lateral Area of Cone is 189.97 yd².
Step-by-step explanation:
Given:
Slant height = 12.1 yd
Diameter = 10 yd
∴ Radius = half of Diameter = 10 ÷ 2 = 5 yd
To Find:
Lateral Area of Cone = ?
Solution:
We know that,
[tex]\textrm{Lateral Area of Cone} = \pi\times Radius\times \textrm{Slant height}[/tex]
Substituting the given values we get
[tex]\textrm{Lateral Area of Cone}=3.14\times 5\times 12.1\\\\\textrm{Lateral Area of Cone}=189.97\ yd^{2}[/tex]
Therefore Lateral Area of Cone is 189.97 yd².
