Answer:
172.70 sq. ft.
Step-by-step explanation:
The surface area of a circular cone is
r = radius of base l = slant height
r = 4.4 and l = 8.1
![SA = 3.14 (4.4^{2}) + 3.14(4.4)(8.1)\\](https://tex.z-dn.net/?f=SA%20%3D%203.14%20%284.4%5E%7B2%7D%29%20%2B%203.14%284.4%29%288.1%29%5C%5C)
SA = 3.14(19.36) + 111.9096
= 60.7904 + 111.9096
= 172.70 sq. ft.
Answer: C, because I’m assuming you meant 84°.
Explanation: 2+6+7 is equal to 15. The three angles of a triangle will always add up to 180, so you need to divide 180 by 15, which is 12. Then, multiply each number (2, 6, and 7) by 12 to get your answer, which is 24, 72, and 84 :)
