Question 1:
All provided options would give the best deal on an item
Answer: Option d [all of the above]
Question 2:

Answer: option C
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
The correct answer is B addition
You will add 4 to both sides then the equation will be 2x=5
