Answer:

7

Step-by-step explanation:

Circunference:

The circunference of a circle with diameter d is given by:

C = d\pi

The diameter of a £1 coin is 22.5 mm.

Each mm has 0.1 cm, so the diameter, in cm, is of d = 2.25. Then

C = 2.25\pi = 7

The circunference is of 7 centimeters.

Pentagon DEFGH is translated 4 units to the right to create pentagon UVXYZ. DE is 5cm long. What is the length of UV?
creativ13 [48]
If a shape is translated (has it's vertex' coordinates moved/changed), then it retains its original values but just has different vertex coordinates.

Thus since DE is equal to UV, then,

DE = UV; substitution:
5=5

Plz solve this question <br>Its urgent.....​
Maksim231197 [3]

Answer:

Step-by-step explanation:

tan Θ + tan 2Θ + √3 tan Θ tan 2Θ = √3

tan Θ + tan 2Θ = √3 - √3 tan Θ tan 2Θ

tan Θ + tan 2Θ = √3 ( 1 - tan Θ tan 2Θ)

(tan Θ + tan 2Θ) / (1 - tanΘ tan 2Θ) = √3

tan(Θ  + 2Θ) = √3

tan 3Θ = tan (\frac{\pi }{3})           we know tan Θ = tan α; Θ = nΠ + α, n belongs to z

3Θ = nΠ + Π/3

Θ = nπ/3 + Π/9 for all n in Z

Answer:

3.

7.608

Step-by-step explanation:

An irrational number is any number which can't be written as a fraction this way. For example, pi and the square root of two cannot be expressed as a fraction of two whole numbers, so they are both irrational.

if we make the respective accounts in the first and second problem we will see that they are irrational numbers

the fourth is a periodic number, which falls within the irrational

the only rational is the third
