Answer:

Step-by-step explanation:

r = d/2

r = 4/2

r = 2

pi = 3.14

Circumference = 2 * pi * r

Circumference = 2 * 3.14 * 2

Circumference = 12.56

Area = pi r^2

Area = 3.14 * 2^2

Area = 4 * 3.14

Area = 12.56

What is the value of x?

timama [110]

Answer:

x = +5

Step-by-step explanation:

The triangles ADB and BDC are similar. Thus it is possible to write an equation of ratios and solve it for x:

x 10

----- = -------

10 4x

Cross-multipying, we get:

4x^2 = 100, which yields x = +5

Semmy [17]

Answer:

Step-by-step explanation:

Substitute: $\frac{\frac{12}{2} +5*6}{3*3}$

Cross out the common factor: $\frac{6+5*6}{3*3}$

Calculate the product or quotient: $\frac{6 +30}{3*3}$

Calculate the product or quotient: $\frac{6+30}{9}$

Calculate the sum or difference: $\frac{36}{9}$

Cross out the common factor: $4$

Which process will create a figure that is NOT congruent to the figure shown? Every point is moved 3 units to the right. Every p

sesenic [268]

Answer:

Every point is moved so that it is 2/3 as far from the y-axis

Step-by-step explanation:

Translation and reflection are "rigid" motions. They do not change the size or shape of the figure, so the resulting figure will be congruent with the original.

Dilation by a factor of 2/3 changes the size, so will not result in a congruent figure.

_____

Here the dilation is in <em>the x-direction only</em>. It is not a transformation we usually are interested in.
