What is the lateral area and surface area of the cone shown below?

Answer:
Lateral Area = 906.3
Surface Area = 461.8
Step-by-step explanation:
1. Find Values:
Diameter = 14
Radius = 7
Height = [tex]\sqrt{19^{2}-7^{2} }[/tex]=17.7
2. Find Lateral Area:
LA= [tex]\frac{1}{3}[/tex] * PI * [tex]r^{2}[/tex] * h
LA = 906.3
3. Find Surface Area:
SA = PI * r * slant height + (2 * PI * r)
SA = 461.8
