The radius is 2 and area = r^2*pi so 4*pi gives you 12.56 so the exact answer would be 12.56 and the answer with pi would be 4 times 3.14!

lys-0071 [83]

Answer:

2–9 7π/6
3–7 2π/3
4–6 π/3
1–4 π/2
5–10 5π/6

Step-by-step explanation:

The angle between numbers on an analog clock is π/6 radians. So, the angles of interest are ...

2 to 9 : seven numbers : 7π/6 radians

3 to 7 : four numbers : 4π/6 = 2π/3 radians

4 to 6 : two numbers : 2π/6 = π/3 radians

1 to 4 : three numbers : 3π/6 = π/2 radians

5 to 10 : five numbers : 5π/6 radians

Answer:

The equivalent ratios are:

16:10

8:5

48:30

Step-by-step explanation:

It is given that the ratios are equivalent ratios. So all the ratios will simplify to the same ratio. We can use this to find the ratios.

given ratio is:

16:10

which simplifies to

8:5

We can observe that the second ratio will be same 8:5

Now,

$\frac{8}{5} = \frac{x}{30}\\x = \frac{8}{5} * 30\\x = 48$

Hence,

The equivalent ratios are:

16:10

8:5

48:30

The triangles are similar. <br> What is the value of x?<br><br> x =

saveliy_v [14]

Answer:

x = 23

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{39}{x-10}$ = $\frac{36}{12}$ = $\frac{15}{5}$ = 3

multiply both sides by (x - 10)

3(x - 10) = 39 ( divide both sides by 3 )

x - 10 = 13 ( add 10 to both sides )

x = 23
