Answer:

No

Step-by-step explanation:

We know that the 3-4-5 and 9-12-15 right triangles are similar. If you add 6 units to the length of each side of both of these triangles, you obtain 9-10-11 and 15-18-21 triangles, which are not similar since 9/15 is not equal to 10/18.

What is the volume of the sphere? (Use 3.14 for π.) 301.44 in.3 2,712.96 in.3 904.32 in.3 1,521.12 in.3
stealth61 [152]

The volume of the sphere is 904.32 inch³.

Step-by-step explanation:

Step 1:

The given sphere has a diameter of 12 inches, so the radius is \frac{12}{2} = 6 m.The volume of a sphere is given by multiplying \frac{4}{3} with π and the cube of the radius (r³).

The volume of a sphere, V = \frac{4}{3} \pi r^{3} .

Step 2:

Here the radius is 6 inches. We take π as 3.14.

The volume of a full sphere, V = \frac{4}{3} \pi r^{3}  = \frac{4}{3} (3.14)(6^{3} ).

\frac{4}{3} (3.14) (6^{3})= 904.32 in³ .

The volume of the sphere is 904.32 inch³, This is the third given option.

An office building has 8 stories above the ground level and 3 stories under the ground level. How many floors apart are the top
vichka [17]

Answer:

11 stories apart

Step-by-step explanation:

We let the "ground" be considered at height = 0

Anything above, is POSITIVE direction

Anything below, is NEGATIVE direction

8 stories are ABOVE, so that would be considered

+8

3 stores are BELOW, so that would be considered

-3

THe difference in height between them is:

8 - (-3) = 8 + 3 = 11

So, that is 11 stories apart (top and bottom)
