A sphere has a volume of 36 (3.14) cm cube. what is the diameter of the sphere

Mathematics

Serga [27]3 years ago
3 0

Answer:

<h2>Diameter = 6 cm</h2>

Step-by-step explanation:

The formula of a volume of a sphere:

V=\dfrac{4}{3}\pi R^3

We have V = 36(3.14) cm³ = V = 36π cm³. Substitute:

\dfrac{4}{3}\pi R^3=36\pi      <em>divide both sides by π</em>

\dfrac{4}{3}R^3=36           <em>multiply both sides by 3</em>

4R^3=108            <em>divide both sides by 4</em>

R^3=27\to R=\sqrt[3]{27}\\\\R=3\ cm

The diameter D = 2R.

Therefore D = 2(3 cm) = 6cm

In parallelogram PQRS, PQ =4x+28, QR=x+31, RS = 10X+4. Which of the
Doss [256]

Answer:

44

Step-by-step explanation:

1) we know that opposite sides of a parallelogram are congruent so

4x+28=10x+4

2) subtract 4 on both sides

4x+24=10x

3)subtract 4x on both sides

24=6x

4)divide by 6 on both sides

4=x

5)substitute for x

length of RS =10(4)+4

length of RD=44

2. Peter drew two rays, AC and AP with A as a common endpoint. Which of the following statements
Ksivusya [100]

Complete question is;

Peter drew two rays, AC and AP with A as a common endpoint. Which of the following statements

might describe Peter's drawing?

I. AC and AP are parallel.

II. PAC is an angle

III. AC and AP are perpendicular

A. I and II

B. II and III

C. I and 111

D. I, II, and III

Answer:

Option B: II & III

Step-by-step explanation:

We are told that Peter drew two rays which are AC and AP.

We are told that A is a common endpoint.

If A is a common endpoint, it means the 2 rays interaction point at A is at an angle.

The angle could also be 90° which means it's possible that the rays AC and AP are perpendicular.

Thus, the correct statements that describe his drawing are: II & III
