For this case we have that by definition, the volume of a sphere is given by:

V = \frac {4} {3} \pi * r ^ 3

Where:

r: It is the radius of the sphere

According to the data we have to:

r = 3 \ cm

Substituting we have:

V = \frac {4} {3} \pi * 3 ^ 3\\V = \frac {4} {3} \pi * 27\\V = 36 \pi\\V = 113

The option that best fits is option B.

Answer:

V=113 \ cm^3

The option that best fits is option B.

Answer:

Step-by-step explanation:

n²+2 where n is number of small squares forming maximum corner square.

in step 1,n=1

step 2,n=2

step 3,n=3

step 4,n=4

when n=1

number of squares=1²+2=1+2=3

when n=2

total numbers=2^2+2=4+2=6

when n=3

total numbers=3²+2=9+2=11

when n=4

total numbers=4²+2=16+2=18

CD is the segment bisector of AB at D. If AD = 4x-1 and DB = 9x-21. what is the length of AD and AB
Artemon [7]

Answer:

AD= 15

AB=30

Step-by-step explanation:

We are given that the Point D bisect the line segment AB

Hence AD = DB

AD= 4x-1

BD=9x-21

Hence

4x-1=9x-21

adding 21 on both sides and subtracting 4x from both sides

4x-4x-1+21=9x-4x-21+21

-1+21=5x

5x=20

dividing both sides by x we get

x=4

Hence

AD = 4x-1

= 4(4)-1= 16-1=15

AD= 15

AB = 2 x AD

     = 2 x 15

  = 30

Find the perimeter of the object <br><br> Help step by step please!
aliina [53]

Answer:

29.42 units

Step-by-step explanation:

<u>1) Find the perimeter around the semi-circle</u>

To do this, we find the circumference of the circle using the given diameter:

C=\pi d where d is the diameter

Plug in 6 as the diameter

C=\pi (6)\\C=6\pi

Divide the circumference by 2

\frac{6\pi }{2} \\= 3\pi

Therefore, the perimeter around the semi-circle is 3π units.

<u>2) Find the perimeter around the rest of the shape</u>

Although it's impossible to determine the lengths of the varied sides on the right side of the shape, we know that all of those <em>vertical</em> sides facing the right add up to 6. We also know that all of those <em>horizontal </em>sides facing up add up to 7. Please refer to the attached images.

Therefore, we add the following:

7+6+7

= 20

Therefore, the perimeter around that area of the shape is 20 units.

<u>3) Add the perimeter around the semi-circle and the perimeter around the rest of the shape</u>

20+3\pi \\= 20+9.42\\= 29.42

Therefore, the perimeter of the shape is approximately 29.42 units.

I hope this helps!
