Answer:

8π

Step-by-step explanation:

If we are given the diameter of this circular fence, then we can solve for the radius. Just take the diameter of 4 and divide by 2 which is 2.

The circumference of a circle is 2πr²

Just plug in the variables and you get 2π(2)² which is 8π

Hope this helps! :)

Answer:

C

Step-by-step explanation:

For the given intervals

( - ∞, - 5) ← use any value < - 5 but not - 5, the parenthesis ) indicates that x is less than - 5 but not equal to - 5

(- 5, - 1) ← - 4, - 3, - 2 can be used but not - 5 or - 1

(- 1, 4) ← 0, 1, 2, 3 can be used but not - 1 or 4

(4, ∞ ) ← use any value > 4 but not 4

Hence

3 can be used in (- 1, 4)

- 6 can be used in (- ∞, - 5)

zero can be used in (- 1, 4)

- 5 cannot be used in any of the given intervals

815 gal/h=_______qt/sec
Nastasia [14]
815 x 360 =  293,400 gal per second.

293,400 gal ÷ 4 quarts = 73,350 quarts per sec.

I'm fairly certain that's right - someone correct me if I'm mistaken.
