Answer:

Option A ( radius is twice the daimeter )

Step-by-step explanation:

The relationship between radius and daimeter is given as

       Radius² = Daimeter    ⇒    r² =  d

And cricumference can be calculated with radius

 As circumference is    2πr

Answer:  c. diameter is twice the radius

For example, if the radius is r = 10 feet then the diameter is twice that and it's d = 2*r = 2*10 = 20 feet.

Due soon!! <br>Find the measure of GE¯¯¯¯¯¯¯¯. A. 14 B. 20 C. 15 D. 16
Nataly_w [17]

Answer:

D. 16

Step-by-step explanation:

GH^2 = GF \times GE

12^2 = 9 \times (9+x - 2)

144= 9 \times (7+x)

\frac{144}{9}= (7+x)

16= 7+x

16-7=x

9=x

GE = 9 + x - 2 = 9 + 9 - 2 = 18 - 2

GE = 16

For the following system, use the second equation to make a substitution for y in the first equation.
VARVARA [1.3K]

Answer:

Option A: 3x + 5x - 4 = 1

Step-by-step explanation:

Given that:

3x + y = 1  ------------- eq1

y + 4 = 5x ------------ eq2

Now for substitution in eq1 we will get a value of y from eq2:

y = 5x - 4

Substituting in eq1 we get:

3x + 5x - 4 = 1

i hope it will help you!

2. Describe the transformation of the graph of f(x) = 6* that yields the graph of f(x) = 6*+1
avanturin [10]
Answer: Translation

The difference between the first equation and the second is that the second is moved one space higher. All of its points will be a unit higher than the other. Because of this change in height, the name of the transformation is a translation

Hope this helps comment below for more questions :)

A cube block has sides 8cm long. A cylindrical hole of radius 3.6 is drilled through the block. Find the volume of the block tha
djverab [1.8K]

Answer:

186.45 cm^3

Step-by-step explanation:

Given data

Side lenght of cube block= 8cm

Radius of cylindrical hole= 3.6cm

Volume of entire Shape= l^3

Volume of entire Shape= 8*8*8

Volume of entire block= 512cm^3

Volume of cylindrical hole= πr^2h

Volume of cylindrical hole= 3.14*3.6^2*8

Volume of cylindrical hole= 3.14*12.96*8

Volume of cylindrical hole= 325.55cm^3

Hence the volume of the block

=volume of entire shape- volume of cylinder

=512-325.55

=186.45 cm^3

-12+5x=15-4x<br><br><br> Please help me :( I need to know how to get the answer as well
tankabanditka [31]

Answer:

We simplify the equation to the form, which is simple to understand  

5x+15=4x-12

We move all terms containing x to the left and all other terms to the right.  

+5x-4x=-12-15

We simplify left and right side of the equation.  

+1x=-27

then divide both sides of the equation by 1 to get x.  

x=-27
