Hi,

Formula for ball volume (considered a sphera) is:

V=\dfrac{4\pi\cdot r^3}3=\dfrac{4\pi\cdot 15^3}3=\dfrac{42,390}3=14,130\ in^3.

3. Which is a function?
OverLord2011 [107]

Answer:

C) {(12,3), (11,2), (10,1), (9,0), (8,1), (7,2), (6,3)} Is a function.

Step-by-step explanation:

The easiest way to tell if a Relation is a Function (in my opinion) is the Verticle Line test. Use your pairs and put them in a graph. Then connect the dots, and if your line at any point touches the graph once, then your Relation is a Function. If it touches the graph more than once, it is not a Function.

Regards!

(1) In the diagram below, AC || DF|| BH || and CB || FE.
Liula [17]

Answer:

Part 1) Triangles ABC, DBG, DEF and BEH are similar

Part 2) \frac{AB}{AC}=\frac{DE}{DF}=\frac{DB}{DG}=\frac{BE}{BH}

Step-by-step explanation:

Part 1)

we know that    

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

In this problem Triangles ABC, DBG, DEF and BEH are similar, because its corresponding angles are congruent by AA Similarity Theorem

Part 2)

Remember that

If two triangles are similar, then the ratio of its corresponding sides is equal

therefore

\frac{AB}{AC}=\frac{DE}{DF}=\frac{DB}{DG}=\frac{BE}{BH}
