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
All you have to do is find the total amount he wrote out checks for and then subtract that from $259.68. The answer is $99.03
YEA I THINK ITS 4 WHAT HE SAID ABOVE ME
Answer:
A) Yes, m=-3 and b = -3
Step-by-step explanation:
The m is the slope of the line and the b is the y-intercept. We can see that the y-intercept is at -3, so that means D and B are not the answer. This leaves us with A and C. The slope of the line is going down instead of up, meaning that the slope of the line is negative. This means that C is not the answer.
Therefore, the answer is A, m= -3 and b= -3.
