Joy has a square picture that is 4 inches on each side. the picture is framed with a length of ribbon. she wants to use the same piece of ribbon to frame a circular picture. what is the maximum radius of the circular frame?

Step 1

we know that

The perimeter of a square is equal to

P=4*b

where

b is the length side of a square

Find the perimeter of the square picture

b=4 in

P=4*4=16 in

Step 2

Find the maximum radius of the circular frame

we know that

the perimeter of a square frame is equal to the circumference of the circular frame

the circumference is equal to

r=2.5 in

therefore

the answer is

the maximum radius of the circular frame is 2.5 in

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
