The sphere's radius is half the radius of the hemisphere. How does the volume of this hemisphere compare with the volume of the
baherus [9]

Answer:

The volume of the sphere is eight times the volume of hemisphere

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

x-----> volume of the hemisphere

y-----> volume of the sphere

z^{3}=\frac{x}{y}

in this problem we have

z=\frac{1}{2}

substitute

(\frac{1}{2})^{3}=\frac{x}{y}

(\frac{1}{8})=\frac{x}{y}

y=8x

that means------> The volume of the sphere is eight times the volume of hemisphere

The coordinates of A, B, and C in the diagram are A (p, 4), B (6, 1 ), and C (9, q). Which equation correctly relates p and q? ↔
aivan3 [116]

Answer:

  D.  p + q = 7

Step-by-step explanation:

The slope of AB is ...

  mAB = (y2 -y1)/(x2 -x1) = (1 -4)/(6 -p) = -3/(6 -p)

The slope of BC is ...

  mBC = (q -1)/(9 -6) = (q -1)/3

We want the product of these slopes to be -1:

  mAB·mBC = -1 = (-3/(6 -p))·((q -1)/3)

  -(q-1)/(6 -p) = -1 . . . . cancel factors of 3

  q -1 = 6 -p . . . . . multiply by -(6 -p)

  q + p = 7 . . . . . matches choice D
