Answer:
Step-by-step explanation:
Volume = πr²h/3 = πr²9/3 = 3πr²
3πr² = 3πy² + 30πy + 75π
r² = y² + 10y + 25
r² = (y+5)²
r = y+5
Well from what I understand about the question, it's asking if there only needs to be 1, how many can there be. so 9
Answer:
x = 3 and y = 1
Step-by-step explanation:
The given equations are :
6x + 14y = 32 ...(1)
6x - 14y = 4 .....(2)
Add equation (1) and (2) :
6x + 14y + 6x - 14y = 32 + 4
12x = 36
x = 3
Put the value of x in equation (1)
6(3) + 14y = 32
18 + 14y = 32
14y = 32-18
14y = 14
y = 1
Hence, the value of x is 3 and y is 1.
