Answer:
- ornament area = 379.8 cm²
- paint needed: 114 bottles
Step-by-step explanation:
The surface area of one cone with slant height s and radius r is ...
SA = πr² +πrs = πr(r+s)
For the cone that is half an ornament, the surface area is ...
SA = (3.14)(4.2 cm)(4.2 cm + 10.2 cm) = 189.9072 cm²
The area of one ornament is the area of two cones:
one ornament area = 2×189.9072 cm² ≈ 379.8 cm²
60 ornaments will be 120 cones, so will have a total surface area of ...
total area = 120(189.9072 cm²) = 22,788.864 cm²
__
If one bottle of paint will cover 201 cm², then the number of bottles of paint required is ...
(22788.864 cm²)/(201 cm²/bottle) ≈ 113.4 bottles
Answer: 
Step-by-step explanation:
Given: The diameter of a large lawn ornament in the shape of a sphere = 16 inches.
Then, the radius of ornament =
inches.
We know that the volume of a sphere is given by :-
, where r is the radius of a sphere.
Now, the volume of the ornament is given by :-
Hence, the approximate volume of the ornament

Answer:
125.6 units = x
Step-by-step explanation:
72
---- = tan 37 degrees, so x = 72/(tan 37 degrees)
x
This comes out to x = 72/0.573 = 125.6 units = x
