Step-by-step explanation:

its hard to determine without the known value of x, but the above would be the equation needed to solve it if you knew what x was
Answer:
V = 1077.566 units²
Step-by-step explanation:
Assuming this is a cylinder, the formula is (area of base) × (height)
or (πr²)(h), simply plug-in the given values:
= (π(7)²)(7)
= (153.938)(7)
V = 1077.566 units²
Since both 4 and 6 are divisible by 2, it becomes 2/3<span />
