Answer:

B

Step-by-step explanation:

If you substitute the x values with 20 then the angles will add up to 180 on both sides. These angles are supplementary which means that they are suppose to add up to 180 degrees.

Answer:

B. x = 20

Step-by-step explanation:

angles on a straight line are supplementary

therefore, 6x+9 + 2x+11 = 180

so, 8x+20=180

8x = 160

x = 20

⦁ A sphere is inscribed in a cube with a volume of 27 cm3. What is the volume of the sphere?
lyudmila [28]

Answer:

≈ 14.14 cm³

Step-by-step explanation:

First find the side length of the cube.

V=S³

27=S³

∛27=∛s³

3=S

Then the volume of the sphere.

V=\frac{4}{3} × π(pi) × r³(radius cubed)

V=\frac{4}{3} × π(pi) × (1.5³)

 =\frac{9}{2}π cm³ ≈ 14.14 cm³
