Answer:
Answer is B, V = π(7)² · 20
Explanation:
the formula for a cylinder is V = πr²h
So, from here you just plug in numbers.
but for "r" you need to take 14 and divide it by 2 since it is in the form of a diameter which is different to a radius or "r".
14/2 = 7
Now, you can plug in numbers,
V = π(7)² · 20
