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

As shown in figure, R is the base radius of the cylinder.
H is the height of the cylinder.
Given: H = diameter of the base of cylinder.
Now, diameter of the base = 2R
So, H = 2R

Answer:
62 miles per hour speed if you drove 325 miles in 5 1/4 hours
Step-by-step explanation:
Using formula:
As per the statement:
if you drove 325 miles in 5 1/4 hours
⇒ miles
and
Time = hours
Then by above formula we have;
miles per hour
Therefore, 61.90 ≈ 62 miles per hour speed if you drove 325 miles in 5 1/4 hours
