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.

What is the slope of the diagonal line on the larger triangle? Explain how you found it.
Stolb23 [73]

Answer: 2/3 is the slope I think and for the same slope thing here is my answer:

We can use similarly of triangles in this case there will be a formation of 2 pairs equal ( angles formed by the y-axis on the parallel lines) angles between triangles formed as the y-axis lines are parallel. So,the slope is the same for both.

Please Help I Don't Understand.
lyudmila [28]

BE and CD are parallel, so the triangles ABE and ACD are similar. Then the following relation holds:

AE/AD = AB/AC

10/(10 + 8) = x/(x + 6)

Solve for x :

10 (x + 6) = x (10 + 8)

10x + 60 = 18x

8x = 60

x = 60/8 = 7/5
