What is the volume of a sphere with a radius, r = 0.5?

Mathematics
1 answer:
sattari [20]2 years ago
8 0

Answer:

V = 0.52 cm³

Step-by-step explanation:

radius r = 0.5 cm

volume V = 0.523333333 cm³

surface area A = 3.14 cm²

circumference C = 3.14 cm

In Terms of Pi π

volume V = 0.166666667 π cm³

surface area A = 1 π cm2

circumference C = 1 π cm

Agenda: r = radius

V = volume

A = surface area

C = circumference

π = pi = 3.1415926535898

Formulas:

Sphere Formulas in terms of radius r:

Volume of a sphere:

V = (4/3)πr³

Circumference of a sphere:

C = 2πr

Surface area of a sphere:

A = 4πr²

PLZ HELP its Triangle Properties and where using the 45º-45º-90º Triangle Theorem and the 30º-60º-90º Triangle Theorem.
den301095 [7]

Answer:

The answer to your questions is below

Step-by-step explanation:

4.-

In a 45°-45°-90° triangle, the length of the legs are "x" and the length of the hypotenuse is x\sqrt{2}

Then, in this problem, the length of the leg is 7 then the length of the hypotenuse will be 7\sqrt{2}

5.- In a 30°-60°-90° triangle, the length of the hypotenuse is 2x, the length of the longer leg is x\sqrt{3} and the length of the shorter leg is x.

In this problem we have the length of the hypotenuse = 20 and find x.

                          2x = 20

                             x = 20/2

                             x = 10

          longer leg = xx\sqrt{3} = 10\sqrt{3}

6.- nonzero

7.- hypotenuse = 20 cm

     Find x

                         2x = 20

                           x = 20/2

                          x = 10

   Shoter leg = x = 10 cm

What is the inverse to 2^x-1
nydimaria [60]

Replace x with y and solve for y~

y=2*

x=2^y

log x = y log 2

y=log x / log 2

Hope this helps and leave a brainliest to help me reach expert ;)

Please someone help me solve this i dpnt know the answer​

<h2><u>Answer With Explanation:</u></h2>

<u>Firstly, let's start with <XOZ: =55°</u>

We know that <ZOQ is 70° and angles on a line add up to 180° so we do 180-70=110 110 divided by 2 = 55 so the 2 angles (XOZ & XOP are 55)

<u>Secondly, <OMN, <MON & <ONM = All are 60°</u>

These 2 angles are joined to create an equilateral triangle which always adds up to 180°

So, there are 3 points to this triangle, therefore we divide 180 by 3 which is 60. The angles are 60°

<u>Thirdly, <QON: =55°</u>

This angle lies on the line XON which needs to add up to 180°

As we worked out before, <XOZ was 55°

So, <ZOQ was already given as 70°

We then do 55+70=125 then 180-125=55°

<QON is 55°

(I'm only in Grade 9 LOL)
