r = (C / π) / 2

Actually the formula of the circumference is Pi multiplied to diameter; where the diameter is equal to twice the radius.

C = π d
d = 2 r
C = π * 2r

If we need to find the radius from the Circumference then

r =  (C / π) / 2

You must differentiate Pi from the number 2 because 2 is part of the radius. This is also to avoid confusion.

For example:  r = 5 ; π - 3.14; find the circumference

C = π * 2r
C = 3.14 * (2*5)
C = 3.14 * 10
C = 31.40

If the circumference is given and the radius is missing, then,

r = (C/π) / 2
r = (31.4 / 3.14) / 2
r = 10 / 2
r = 5

A triangle has squares on its three sides as shown below. What is the value of x? Three squares having side lengths 3 cm, x cm,
Pani-rosa [81]

Answer:

The value of x is 5 centimeters.

Therefore, option 3 is correct.

Step-by-step explanation:

A triangle has three sides 3,x and 4 cms

Since the triangle is right angle triangle  so, it will follow the Pythagoras theorem:

hypotenuse^2=side^2+side^2    (1)

We have been given three sides x,3 and 4

On substituting the values in (1) we get:

x^2=3^2+4^2

x^2=9+25

\Rightarrow x=5

Hence, the value of x is 5 centimeters.

Therefore, option 3 is correct.

Please look at the attachment for the figure.
