You could first solve for y, assuming x is 0, and y = 6. Then solve for x, and that means y = 4.
Answer: 
Step-by-step explanation:
1. If you join the top part and the bottom part of the figure, you obtain a sphere. Then, you must apply the formula for calculate the surface area of a sphere:

Where r is the radius (
)
2. Then:

3. The formula for calculate the suface area of the red part, which is a cylinder, is:

Where h is the height (h=32mm)
4. Then:

5. So, the total surface area is:

The answe would be 300 because, the perimeter of the windows is 12, then you have to multiply 25 to 12 then bam you get 300, yay!
The probability of randomly drawing either a red marble or a green marble is 80%
The probability of drawing a green marble is the same as the probability of drawing either a red or a blue marble.
