Explanation
The surface area of a cone is given by:
[tex]S=\pi\cdot r^2+\pi\cdot r\cdot\sqrt{h^2+r^2}.[/tex]
Where h is the height and r is the radius.
In this problem, we have:
• r = 8 yd,
,
• h = 14 yd.
Replacing these data in the equation above, we get:
[tex]S=\pi\cdot(8\text{ }yd)^2+\pi\cdot8yd\cdot\sqrt{(8\text{ }yd)^2+(14\text{ }yd)^2}\cong606.32\text{ }yd^2.[/tex]Answer
B. 606.32 yd²
