Answer:

Radius of the sphere = r

<u>Volume of sphere:</u>

  • V₁ = 4/3×πr³

Radius of the hemisphere = 2r

<u>Volume of the hemisphere:</u>

  • V₂ = 1/2×4/3×π(2r)³ = 1/2×8×4/3πr³ = 4V₁

The volume of the hemisphere is 4 times greater than the volume of the sphere

FORMULA:

Volume of sphere = 4/3πr³

Volume of hemisphere = 2/3πr³

ASSUMPTION:

Radius of hemisphere = r

Radius of sphere = 1/2r

ANSWER:

Now, Volume of hemisphere = 2/3πr³

And Volume of sphere = 4/3π(1/2r)³

  • 1/6πr³

So, their ratio—

  • 2/3πr³ × 6πr³
  • 4 times.

Answer:

the third one and the last one is correct

Step-by-step explanation:

we already know the second one is wrong because of it's set up.

just replace the points (-1,7) into each equation. if it doesn't work then move on to the next one. if it does work, then use that same equation except this time to the coordinates (2,4)
