A positive number divided by a negative number gives you a negative number for example 12 is positive but the three is negative so our answer has to be negative

For a cylinder

$V_\textrm{cyl} = \pi r^2 h$

Since $h = 2r$

$V_\textrm{cyl} = 2 \pi r^3$

We know that's 64 cubic meters,

$64 = 2 \pi r^3$

The sphere's volume is

$V = \frac 4 3 \pi r^3 = \frac 2 3 (2\pi r^3) = \frac 2 3 (64) = \dfrac{128}{3}$

Answer: 128/3 cubic meters

That may be that choice peeking out at the bottom; can't really tell

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Answer:

0 < x ≤ 1 would be f(x) = 1

1 ≤ x ≤ 2 would be f(x) = x

2 < x ≤ 3 would be f(x) = 3

3 < x ≤ 4 would be f(x) = 4

step-by-step explanation:

0 < x ≤ 1 is over the line 1

1 ≤ x ≤ 2 x is the slope of 1

2 < x ≤ 3 is over the line 3

3 < x ≤ 4 is over the line 4

Not mine just copied the answer from the comment of the person who gave no help all the credit goes to the person who commented the correct answer
