Answer:
<em>$195</em>
Step-by-step explanation:
15a + 12c
5 adults and 10 children means a = 5 and c = 10
15a + 12c = 15(5) + 12(10) = 75 + 120 = 195
I first change the fraction into a decimal which give me 3.5. then plug it in and you'll get 21.991 meter. Hope that helps.:)
I believe also 115 degrees bc they’re vertical angles
Answer:
LA = 1,187.5 ft^{2} and SA = 1,803.3 ft^{2}
Step-by-step explanation:
We are given, the radius 'r' of the cone is 14 ft and the slant height 'l' is given by 27 ft.
Now, we know that the formula for the lateral area =
i.e. lateral are =
i.e. lateral area = 1187.52 ft^{2}
Hence, lateral area rounded off to nearest tenth is 1187.5 ft^{2}.
Next, we know the formula for surface area of a cone =
i.e. surface area =
i.e. surface area = 1803.27 ft^{2}
Hence, the surface area rounded off to the nearest tenth is 1803.3 ft^{2}.
