Answer is B, V = π(7)² · 20

Step-by-step 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

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
