1. The surface that will be exposed to the rain is the lateral surface of the cylinder and the hemisphere.
2. The lateral area of the cylinder is a rectangle with height equal to the height of the cylinder and width equal to the circumference of the base of the cylinder.
3. the circumference of the base = 2
r=2**5=10
so the lateral area = 10*h=10*40=400 (
)
4. The surface area of a sphere is
so the surface of the hemisphere =
()
5. Total area exposed = 450

Answer:
The length of TR to the nearest tenth of a foot is 4.9 feet.
Step-by-step explanation:
Δ RST is a Right Angle Triangle at
∠ T = 90°
∠ S = 66°
ST =2.2 feet
To Find:
TR = ?
Solution:
In Right Angle Triangle Δ RST we will apply Tangent Rule
The length of TR to the nearest tenth of a foot is 4.9 feet.
