Answer:

A. 54 pie cm³

Step-by-step explanation:

height of the cylinder = 6 × radius of one sphere.

= 6 × 3

= 18 cm

as we can see 3 spheres make up the height of one cylinder,

height of one sphere = 6 cm (3 + 3)

with three spheres it becomes = 6 × 3

= 18 cm

volume of a cylinder = $\pi$ r² h

= $\pi$ × (9)² × 18

= 27 × 6 $\pi$

volume of a sphere = 4/ 3 × $\pi$ 3³

= 36 $\pi$

for 3 spheres

volume = 3 × (36 $\pi$ )

= 27 × 4 $\pi$

volume of the empty space

= volume of cylinder- volume of 3 spheres

= 27 × 6 $\pi$ - 27 × 4 $\pi$

= 27 $\pi$ ( 6 - 4)

= 27 × 2 $\pi$

Ana drew a map of the Panama Canal. In the scale Ana used for the map, 4 centimeters represents 20 kilometers. The actual length

yawa3891 [41]

Answer:

Length of the canal on the map is 16.4 centimeters.

Step-by-step explanation:

If actual length of Panama Canal = 20 kilometers

and length of the canal on map = 4 centimeters

Then scale factor = $\frac{\text{Length of canal on map}}{\text{Actual length of canal}}$

= $\frac{4}{20}$

= $\frac{1}{5}$

If the actual length of Panama Canal = 82 kilometers

Then the length of canal on the map = Actual length × Scale factor

= $82\times \frac{1}{5}$

= 16.4 centimeters

Therefore, length of the canal on the map is 16.4 centimeters.

PLEASE HELP ME WITH THESE FOUR QUESTIONS TYSMMM!!! THANK YOU

Dima020 [189]

Answer:

$107^\circ, 133^\circ, 20^\circ, \text{and}, 23^\circ$

Step-by-step explanation:

9. For the lines 'm' and 'n' to be parallel the sum of interior angles should be 180 degrees that is:

$x+73^\circ=180^\circ$

$x=107^\circ$

10. For the lines 'm' and 'n' to be parallel the alternate exterior angles should be equal that is:

$147^\circ=x+14^\circ$

$x=147^\circ-14^\circ$

$x=133^\circ$

11. For the lines 'm' and 'n' to be parallel alternate angles should be equal that is:

$180^\circ-3x=2x+20^\circ$

Solving for 'x' we get:

$180^\circ-20^\circ=3x+2x$

$5x=160^\circ$

$x=32^\circ$

12. For the lines 'm' and 'n' to be parallel corresponding angles should be equal that is:

$(7x-11)^\circ=(4x+58)^\circ$

$7x-4x=58^\circ+11^\circ$

$3x=69^\circ$

$x=\frac{69}{3}=23^\circ$

Help plzzzzzzzzzzzzzzzzzzzzzzz

wel

HMMMMMMM...It could be C...

An Arc is the the end of the circle, the OUTER rim..do you get what I'm trying to say? SO, if you look at AC, it looks like an arc.

Hope this helps!
