Answer:
y = -16
Step-by-step explanation:
Given that,
y varies directly with x. Mathematically, we can write it as follows :
or
Where
k is constant
Put y = 12 and x = -3 to find k. So,
Now put k = -4 and x = 4. So,
So, the required value of y is equal to -16.
All cross sections are circles because a sphere has only circles for cross-sections.
